BackgroundThe B58 engine, introduced with the F-series, has proven to be a real gem of an engine, capable of high outputs with great character. However, there are a few week points that needs addressing, both for performance and reliability. The B58 comes equipped with a water-to-air charge cooler that is coupled a with front-positioned heat exchanger (water radiator). The heat exchanger serves to cool the water circulating through the charge air cooler, which in turn helps dissipate heat from the charge air before it enters the engine. The charge air cooler is integrated into the intake manifold on the B58, making it an intricate and dense construction, demanding accuracy in the design and execution by us as an aftermarket producer.
Challenges with the factory components
Owners of tuned B58 engines often confront the issue of rapid heat soak in the charge air cooling system, particularly when the vehicle is used for track days. Elevated intake air temperatures may prompt the ECU to decrease the power output, or even switch the car into limp-home mode. Regular spirited street driving can also cause similar issues.
Additionally, the factory installed direct injection system, with its obvious benefits, is not well suited for high horsepower applications or ethanol flex fuel usage. To be able to inject more fuel, many turn to installing port fuel injector spacers between the intake manifold and the cylinder head. The downside with this solution is that it positions the injectors in a funny angle. As a result, the fuel hits the walls of the intake runners, leading to potential fuel puddling.
As is often the case, factory components can become limiting factors when you strive for high power levels, particularly in terms of airflow. The factory (OE) intake manifold is such a component, that not only restricts airflow but also poses a significant risk of cracking under high boost levels, due to its plastic construction.
The do88 solution
Bar & Plate coreOur manifold features a Bar & Plate design air-water core, which incorporates densely stacked cooling fins, offering great heat transfer. The core is precisely 102 mm (4 inches) thick, maximizing its effectiveness for this specific application. Both the air and water fins´ characteristics have undergone careful evaluation to achieve the ideal balance between optimal cooling and airflow.
Innovatively designed cast end tanks
The charge air and cooling water are evenly distributed across the core through carefully designed, cast end tanks. The development of these end tanks involved a comprehensive process, including 3D-scanning, multiple design iterations followed by Computational Fluid Dynamics (CFD) analysis and 3D-printing, before arriving at the finalized prototype. We opted for cast end tanks over CNC-machining. Casting allows complex shapes that better serves the desired function. To us, maximum performance supersedes the bling factor!
Engine Cover Compatibility
A goal during the development of our do88 manifold was to keep compatibility with the standard engine cover. It goes without saying, many enthusiasts prefer to maintain the original appearance of their engine bay if possible. With this in mind, we invested significant effort to design a charge air cooler that not only makes a massive performance upgrade, but also have the possibility to use the engine cover. We managed the challenging task of accommodating our manifold under the engine cover.
Moreover, it is possible, with modifications, to also integrate our auxiliary fuel rail. To do this, the sound-dampening material beneath both the engine cover and the hood must be removed. Additionally, the standard engine cover mounting pins must be replaced with longer ones, which we include in our kit. Note that installing the engine cover in this elevated position brings it very close to the hood; slight trimming or reshaping of the hood's support structure can be done to increased clearance. We have verified this compatibility exclusively on the BMW 340i F30/F31 models.
The devil is in the detail and to date, this unique feature sets the do88 kit apart from the competition. High performance builds tend to be made by enthusiasts that value the appearance equally as high as the sheer performance without compromise.
Key Features
Versatile Manifold Design: From Fuel Injection to Power ModificationsOur manifold outlet tank is pre-configured to accommodate auxiliary port fuel injection. A custom-made fuel rail with female AN-8 threads is available to purchase separately, this easily installs to the outlet tank. We designed it for compatibility with Injector Dynamics ID1050x-34-14 or Bosch EV14XK (short) fuel injectors. If you opt to not use port fuel injection, we provide injector blanking plugs for your convenience. Additionally, each cylinder runner on the outlet tank is equipped with a 1/8 NPT port, suitable for nitrous or methanol injection - a commonly used power modification for the B58 engine (sealing plugs are included).
Extra Measurement & Vacuum Ports
Integrated into the side of the manifold inlet tank, do88 has incorporated a 3-port pad directly into the casting. This feature offers the flexibility to measure additional parameters or serve as an extra vacuum source. Should you choose not to utilize these three 1/8 NPT ports, sealing plugs are provided in the included hardware kit.
Advanced Thermal Management
Included with the intake manifold is a special thermal barrier spacer, engineered to insulate the aluminum intake manifold from conductive heat transfer from the cylinder head. This barrier effectively lowers intake air temperatures (IAT´s), enhances the efficiency of the charge air cooler, and helps minimize the issue of heat soak. Unlike the OE plastic intake manifold, the do88 manifold is made from aluminum, capable of withstanding higher boost pressures. The thermal barrier spacer reduces the conductive heat transfer, otherwise typical to aluminum components. The spacer features a robust seal, achieved through custom-made, high-specification FKM-silicone O-rings. These O-rings are installed in precision-machined grooves for a secure fit. This approach offers a significantly better seal compared to other competitors´ methods, which often rely on less reliable sealing agents.

Soft yet supportive
Size: Queen
I have been through 4 other pillows in the last year trying to find one that supports but isn't too firm.
I gave this one a shot and am really loving it. It's soft, comfortable, supports without hurting my neck or shoulder. I am short so some pillows are too high for me. I'm mainly a siide sleeper, this pillow is great as I can place my head anywhere not just middle of very end like the other pillows I was trying. I can sink into it a little yet still have support and it doesn't crush down.
It comes with more filler but haven't needed it. I put it in the dryer on ultra delicate when I first got it and it fluffed nicely.
Very happy with this product as I am now getting more sleep.

Absolutely in love with this pillow!
Size: King, Size: King
I’m so excited about this purchase — this pillow turned out to be amazing! I’m a side sleeper most of the time, and the way the edges are designed makes it incredibly comfortable and supportive. What really surprised me is that even when I slept on my back (which I normally don’t like), I felt super comfortable. I actually woke up still lying on my back — and that never happens! I know it’s healthier to sleep that way, so I’m really happy about that and hope it becomes a new habit.
Before this, I tried a few regular memory foam pillows, but they always felt too firm and my neck would get tired. This one, with the shredded memory foam, is so soft and cozy — it molds perfectly without feeling lumpy. The King size is perfect too — my little Pomeranian loves to rest his tiny head next to mine on the pillow. I don’t know why he does that, but it’s adorable.
And I have to mention the packaging — the box was so high-quality and beautifully made that I just couldn’t throw it away. I’m definitely keeping it to store something in.
Overall, I’m super happy with this pillow and will be ordering a second one soon. I only got one to test it out, but now I’m totally convinced. Thank you for such an awesome product!

This is Truly the Best Pillow!
Size: Queen
This is the side sleeper version of the best pillow out there.
My 26 year old son was always complaining about his pillow and his neck and back hurting. About every year I’d buy him the next “best” pillow promising to be the best but they never worked for him. I read an article saying THIS pillow was the “Goldilocks” of pillows. So since he sleeps in all positions, I got him the regular shaped pillow. The next morning after his first night with the pillow, he came out of his room talking about how wonderful his pillow is. Same thing the next morning. And the next. And the next. Then I thought to myself, my current pillow is the best I’ve had but I’m not in love with it. But I’m a side sleeper so I purchased this particular contoured pillow for me. NOW I UNDERSTOOD WHAT MY SON WAS TALKING ABOUT. I became the person who went on and on about my pillow. Until my husband told me to replace his with one of these side sleeping versions for himself. And he loves it. Then we got a regular pillow (for those who sleep in all positions, but this same company) for our guests. My best friend came to visit, immediately noticed the pillow upgrade from previous visits and when she returned home, she purchased one for herself.
This pillow is like a feather pillow except it is filled with tiny squares of memory foam. And it comes with an extra pack of stuffing, so you can add or remove stuffing to customize it perfectly for you. None of us in the house added filling, and my son removed some that came with his pillow. I also sleep with a body pillow and have for years. And I was wishing this came in a body pillow version until I realized I could make my own. I bought a zippered body pillow case. The larger size. I think it was 54 inches long. And I bought a king size pillow and used the extra stuffing pack that came with that pillow along with the 4 packs that came with the other pillows that we didn’t use. Though you could probably do the same thing with two standard size pillows. These pillows are on the expensive side but they go on sale during every holiday. That’s when I purchase them. Oh and my body pillow is HEAVEN. Between that and the pillow, I spend my nights in fluffy cloud goodness.
