PRODUCT INFORMATION
INTRODUCING CSF'S NEW 'SUPER MANIFOLD' FOR THE A90/91 SUPRA AND BMW G-SERIES B58 ENGINE
CSF is proud to announce its most advanced cooling system to date – the new Charge-Air Cooler Manifold for A90/A91 Toyota Supra and BMW G-Series (B58).
With well over 1,500 hours of design, prototype development, machining, and testing, CSF, along with partners VF Engineering (USA) and Custom Plenum Creations (Australia), has now brought a state-of-the-art CNC machined, high-performance Charge-Air Cooler Manifold to the B58 platform for Mk5 Supra and BMW models. This product solves what has been commonly known as a weak link of an otherwise impressive new engine platform.
With the larger and more efficient water-to-air intercooler performance, lower pressure drop across the system, included fuel rail, kit for top feed port injection, and several other industry-leading features, the CSF Super Manifold will allow B58 owners to maximize the performance of their vehicles and push the limits further than what has been previously possible with this new platform.
CSF pressure tests each #CSF8200 / #CSF8200B / #CSF8200C manifold at 60-70 PSI for a period of 2-3 minutes during the Quality Control and Inspection process. The CSF manifold is not designed to operate above 60 PSI. Any users who chose to operate their vehicle with the CSF manifold over 60 PSI does so at their own risk. Operation at these pressure levels will void the CSF Limited Lifetime Warranty.
Direct replacement for OEM part numbers 11618647977 & 17101WAA01. Only suitable for models equipped with the B58C (2nd Gen.) engine.
FEATURES
- Utilizes a high-performance, motorsports-grade bar/plate air-to-water intercooler core that's double the capacity of the OEM core (12 rows of water cooling vs. OEM 6 rows).
- Significantly lower pressure drop across the core compared to OEM.
- Designed in SolidWorks using computational fluid dynamics (CFD).
- Integrated air divider in inlet tank evenly distributes airflow throughout the core.
- Easy access to spin-off oil filter for quick oil changes – no need to uninstall manifold every oil change.
- Counter balanced design for optimized airflow.
- Integrated sensor pad with three 1/8″ NPT ports to measure additional parameters.
- Included optional fuel rail for top feed port injection.
- Individual port injection bungs on each cylinder runner (comes pre-plugged).
- Individual 1/8″ NPT ports on the top of each cylinder runner for nitrous or meth injection. This allows for even spray distribution and control for maximum performance and engine protection.
- Individual 1/8″ NPT breather ports for both inlet/outlet water connections on back of manifold for easy air-bleeding of the system.
- Plug-and-play design, requiring no modifications to install.
- Includes hardware and installation kit with picture diagrams containing 28 different parts for easy Installation.
- Can be used with OEM or aftermarket engine covers (with OEM connections).
- Comes finished in Raw Billet Aluminum (#CSF8200) – made by world-leading automotive machinist Custom Plenum Creations in Australia.
- Optional 'Thermal Black Heat Dispersion Powder-Coating' finish (#CSF8200B) or custom finishes available (#CSF8200C).
CSF CREATES THE MISSING LINK TO MANIMUM B58 PERFORMANCE
The newer 2nd gen B58 (B58C) engine, found in the Mk5 Supra, has already been proven to be an incredible platform for performance enthusiasts – taking the performance and motorsports industry by storm in just a couple of years since its release. In a short amount of time, performance enthusiasts have already started to more than double the stock engine output – now pushing through 700whp, 800whp, and looking into the elusive 4 digit 1,000whp mark.
The OEM water-cooled charge air cooler intake manifold for the B58 engine is adequate in cars with little or no modifications, but starts to really show an apparent weakness in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. Also, the OEM intercooler system has been known to suffer from heat soak in demanding racing conditions such as time attack, endurance racing, drag racing, and drifting, as well as spirited driving on the street. This can cause the car to pull timing out of the engine due to high intake air temperatures (IATs), and then can cause “limp mode” once temperatures reach a certain threshold, as the vehicle’s ECU will cut power to protect the engine.
DESIGN AND ENGINEERING
CSF conducted extensive testing on the dyno with R&D partner VF Engineering to ensure performance improvements before going into production with the new manifold. We performed over 50 dyno runs on the same car, on the same day, in relatively hot ambient conditions (~90°F) comparing the performance of the CSF Charge-Air Cooler Manifold to the OEM. Both the CSF and OEM cooler went through roughly 25 back-to-back dyno pulls every 30 seconds to measure the performance of the car overtime, resistance to heat soak, recovery time, and the effect on the turbo system duty cycle.
Reputable automotive website and performance part testing specialist, MotoIQ, was on site to witness and assist in organizing the testing to validate the accuracy of the claims made by CSF on the improvements and benefits of the upgraded manifold. The results were published independently by MotoIQ and are now available on their website.

The results were published independently by MotoIQ and are now available on their website.
SUMMARY OF TESTING
- Faster recovery of intake air temperatures.
- ~30°F reduction of intake air temperatures (IAT’s) compared to OEM.
- Less pressure drop compared to OEM core putting less stress on the turbo system, and allowing more boost to be made at higher targets.
- Avoided going into limp mode after prolonged demanding conditions, simulating motorsports use.
- On a stage 2 car with bolt-on upgrades, making ~400whp, comparing dyno run 19 between CSF and OEM, an increase of ~26whp and 11wtq were achieved (the performance increase and delta between CSF and OEM will be bigger as power is increased in the vehicle).
YOU ASKED, CSF LISTENED - ALL THE FEATURES YOU NEED TO PUSH THE LIMITS
During the final design stage of CSF’s new manifold, owner of CSF, Ravi Dolwani, hopped on a plane to Texas to attend the TX2K drag race invitational. Included at this year’s event was an A90 Supra class. Ravi went to speak with Supra owners and find out what they wanted out of an upgraded performance manifold. He came back to CSF following the race weekend, and worked with long time design partner and CSF customer, VF Engineering, to implement a host of features that took the performance benefits and capabilities of the new CSF manifold to an even higher, industry-leading level.
INDIVIDUAL NITROUS / MENTHANOL INJECTOR PORTS
On the outlet tank, each cylinder runner has a 1/8th NPT port which can be used for nitrous or methanol injection (a popular power modification on the B58 engine). The CSF manifold allows for maximum spray control and even spray distribution throughout the engine. A nitrous system set-up specifically for the CSF manifold will be coming soon from industry leaders Nitrous Express.
A handful of cars at TX2K had blown their engines due to the way their nitrous systems were plugged into their vehicles. With the OEM plastic manifold, a single spray system is most commonly used as threading into plastic to insert an injector node is already very difficult to install properly. The single fogger system, more often than not, will create unequal distribution of spray in the engine, either giving some cylinders too much or too little spray. This will increase the chance of severely damaging the engine.

This will increase the chance of severely damaging the engine.
TOP FEED PORT INJECTION WITH INCLUDED FUEL RAIL
An extruded fuel rail is included with the CSF manifold. It can be attached to the outlet side of the manifold. The AN-8 fuel rail comes with feed and return -8 internal hex plug fittings from Radium Engineering for a plug and play installation.
- Fuel rail aperture for each cylinder is an optimized 7mm opening for compatibility with most commonly used high performance injectors
- CSF recommends using Injector Dynamics (ID) injectors for the best performance – the most commonly used injector for this engine has been ID model # 1050.34.14.14.6 (qty 6)
- Anodized CNC machined injector hats (qty 6) are included in the supplied hardware kit to accommodate short height injectors aka “shorties”
VACUUM AND PARAMETER PAD
On the side of the manifold inlet, CSF has included a 3 port pad into the machining of the tank. This can be used to measure additional parameters or as an additional vacuum source. These three 1/8th NPT ports can be plugged with the included hardware kit if they are not used.
EASY ACCESS TO SPIN-OFF OIL FILTER WITH COUNTER BALANCED DESIGN
Imagine having to remove your manifold every time you wanted to change your oil, especially if your vehicle is used in motorsports where oil changes occur more often. CSF thought of its customer base during the design phase and have incorporated a recessed design towards the back of the manifold that for allows easy access to the spin-off oil filter. A counter balanced design protrusion above the recess was simulated in SolidWorks CFD software to ensure smooth air delivery into the rear of the core for the best possible cooling effect.
AIR INLET DIVIDER
Another exclusive feature of the CSF manifold is the inclusion of an air divider welded into the inlet side tank of the manifold. With the length of the design, the engineers at VF Engineering wanted to make sure that the volume and velocity of air received to the back of the manifold to cylinder areas four, five, and six would be equal to the airflow passed through the front half of the manifold for cylinders one, two, and three. After extensive simulations in SolidWorks CFD software, an air divider was added to the design to ensure the best possible and equal cooling performance to each cylinder of the engine.
BREATHER PORTS FOR INLET/OUTLET OF WATER TANKS
Two 1/8th NPT ports are located on the top of the back water plate. These can be used to measure inlet/outlet water temps as well as used as breather ports to help in the bleeding procedure to ensure all air has been cleared from the water system. 1/8th NPT plugs come included in the supplied hardware kit. Please follow OEM BMW or Toyota bleeding procedure which takes roughly 15 minutes to complete.
HARDWARE KIT, WELL THOUGHT-OUT INSTRUCTION MANUAL & THE ABILITY TO INSTALL OEM AND OEM-STYLE ENGINE COVERS
Included in the supplied hardware kit is several brackets, bolts, washers, and mounting posts to be able to install the OEM and OEM-style engine covers. This is an industry-exclusive feature to the CSF x VF Engineering design, and was extremely difficult to not only engineer, but to manufacture as well. An array of items come vacuum packaged with corresponding letters listed on an easy to use Bill-of-Materials List (BOM) along with exploded diagrams and a simple order of operation procedure list to follow for installation. Made with racers and DIY enthusiasts in mind.
CSF’s most popular custom finish, Thermal Black Heat Dispersion Powder-Coating is now available as a standard finish option. This offers faster turn around time for orders.

LIFE-CHANGING. The only chair you'll ever want or need.
Color: Black
So... This chair has absolutely changed my life. I don't often leave reviews, but this is WORTH IT. I want one in every room in my home. Just as the other reviewer with the 'life-changing chair' title to their review: I've had 100% the same experience - especially as someone who sits 3,000 different ways w/ ADHD lol. So, in addition to agreeing with all those comments...
I'll just add a few more thoughts here to further convince you:
- I received the Cream/Teddy one as a Christmas gift and have literally have looked forward to sitting it in for work every. single. morning. for work.
- I *ALSO* purchased a second one in the black velvet one to gift to my partner and his experience has also been 'life-changing.' (The black velvet is definitely sleeker looking, almost a teeny slippery, but just beautiful fabric. Love it. A note here: the fabric came with a crease, which steamed out no problem.)
- I sit and edit websites and photo/video everyday, all day, for work, and I also spend a good chunk of my time gaming with my partner. (Now we are *both* very comfortable for those longer 5+ hour sessions.)
- Previously I had tried the viral criss-cross chair and while it was cute and great at first, it just didn't hold up and started causing numb spots on my lower back after ~2 hours. Not an all-day chair at all. This one has solved all back issues for me!
Size: definitely big & the back is quite a tall height but it makes you feel cozy, supported, *and* you can lean back, recline, adjust every little bit you like, have space for a velcro cat, sit criss-cross or 3,000 other ways as a ADHDr trying to sit all day, lol, etc. -- all things I was looking for in an upgrade. For reference, it fits someone 5'5" to 6"5" just as comfortably. I'd say it feels on the bigger side for someone under 6 foot, but personally, I love that. It's like a real adult chair - much needed if you sit for 6+ hours a day.
Leg rest: Easy to flip out, I love using this so you can sit cross cross AND lean back, or just as extra 'accommodate the cat' space.
Noise level: the arms clicking down/adjusting is loud, but I don't find myself adjusting them all that often. Especially when my cat claims this chair first, anticipating the start of our work day.
Comfort level: 100% and 2.5-3 months in, it's still going strong and I'm more obsessed each day.
*To the store: THANK YOU for making this chair, please never stop.
*To the person reading this review: BUY IT. Let this be the review to convince you - your cat will take over the chair and you'll have to fight over it, it's that comfy. I mean, they know best, do they not?

Beautiful sturdy, cozy chair, BUT…..
Color: White, Color: White
Updated review.
I was so excited to get this chair that I jumped the gun and wrote the review prior to spending more time seated.
I only have one issue, which is the back bottom of the seat cushion. That’s a big deal. It appears so thick, fluffy and inviting, however, when I sat in it for a couple of hours it completely went flat in the back feeling like I was sitting on a board. I’m 5’4” 180 lbs, which means my feet don’t touch the floor so adding a cushion will elevate me a little more. I’m OK with that but it’s going to ruin aesthetic of the chair which is which is not ok. I do love the idea of this chair. It’s design and the color. I wish the seat cushion had a zipper, which would eliminate my issue. I’d say if you’re someone who has to spend a lot of hours in this chair, you probably won’t like it. I do like the reclining back and the foot rest. It is comfortable to lay back but that doesn’t change the issue in the back bottom of the seat cushion.
I absolutely love this chair, I didn’t want to get up. It’s beautiful and cozy. Assembly was easy as I’ve assembled chairs before. I changed the wheels to a double roller blade easy on hard wood floors. I also scotch guarded the entire chair. This chair is sturdy and well made.

just get it and stop second guessing
Color: White, Color: White
I reallllly love this chair. I almost talked myself out of it because of some of the bad reviews here and there but i’m glad i listened to a majority of the good reviews, because this chair is perfect.
shipping: it was super fast. it came 5 days earlier than expected. I got it on a Monday when it said it’d be here on Friday
packaging: double boxed and bubble wrapped. Didn’t find any dings or scratches on anything. all parts were there including instructions
assembly: my boyfriend put it together in 40 minutes. We didn’t have any issues zipping up the back cover like other reviews said and he said it was easy instructions to follow, and easy to put together.
size and comfort: it’s bigger than the pictures let on! I’m 5’3 135lbs and feel like I’m sitting on a giant cloud. The comfort is 10/10. I just had a chair with basicslly zero butt cushion which i cannot have while working from home 8+ hrs a day in a chair. Comfort was the most important for me and I finally can’t feel the flat seat under me. I can’t express how comfy it is.
Functions: can move the arm rests up and down. adjust the back to tilt all the way back to a sleeping position or fully upright which i didn’t even realize was a function! The only thing with the armrests; if you’re wanting your pet on it (like advertised) when the arm rests is put down there is a big gap that isn’t comfortable for animals (as pictured) so I have to put a blanket or pillow there for my small dog to lay comfortably.
I’m obsessed with the fact I can sit cross legged, normally, laying down, sprawled up, or legs up. I have room to sit however I want, and the foot rests helps a ton with feeling even more comfortable.
Overall, I’d get this chair 10x over. Not only do I work from home and spend hours in a chair, but I spend additional time playing video games so a good quality chair is very important to me. This has began to help fix my posture and back and neck issues.
Get it!!!

If You Sit Weird Like Me… Just Buy This Chair
Color: Galaxy Black
I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far.
I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway.
I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it.
The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets.
Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple.
The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting.
It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold.
I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair
Color: Pink
I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!
