Overview:
The new single plane intake manifold is designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The carburetor-mounting pad is designed to accept all stock or aftermarket square-bore carburetors with manual or electric chokes.

Also, these manifolds will work with any SBC engine equipped with aftermarket cylinder heads, as long as they have a standard port flange opening and mounting bolt locations.
Features:
- Single Plane with Isolated Plenum
- Square Bore Carburetor Mounting Flange
- Isolated Water cross-over
- Power band: 2500-7500 RPM

Very nice look and perfect "sheen"..
Size: 16 Fl Oz (Pack of 1), Style: Fresh
I've been an avid detailer for 30 years. And I do love the chemicals aspect of it. I've tried many products, and the vast majority of them aren't very good. Mind you, I was starting out detailing back in the 80's, when you had a VERY limited amount of products to rely on (And yes, I remember the very first days of Armor-All when it would CRACK your dash.. Those days are, of course, long gone.
But I have been a big fan of Chemical Guy's products, and have written many reviews on here about their other products.
This Total Interior, I have to say, has met or exceeded my expectations.
Tip and note: Always wear nitrile type gloves whenever using any chemicals for detailing, repair, etc A garage isn't complete without nitrile gloves and an air compressor.. Enough on that.
First off, they say you can use it on glass, and this would replace a lot of other cleaners and protectants, I'm not sure I would use anything to clean glass other than Invisible Glass. I've tried them all, and to me, Invisible Glass is my go-to and ONLY glass cleaner.
Secondly, this DOES have a UV protectant in it, which of course, led me to purchase this. I've said on here before that if you are going to take the time to detail, and make the effort, you should not waste your time with products (Especially interior products) that don't protect the interior from UV damage.. The sun is a killer on leather and plastic.. (And paint, over time).. So if you're going to use any products on your interior make sure they have UV protectants.
Thirdly, they say you can use this on Leather. I for one, after working with it, probably wouldn't use it on my leather, I prefer some other products for that, and yes, don't bother using ANY leather treatment unless it has a UV protectant in it, or at least follow it up with something that DOES have a UV protectant. I personally wouldn't use this on my leather. I would use Chemical Guys' Sprayable Leather Cleaner and Conditioner (no UV protectant), and then follow it with Klasse Interior as the Klasse has a UV protectant. The Klasse is also a water based formula (The original was oil based) and it also helps to tighten the leather a bit too.. Those two in combination make a nice look.
What's nice about this Total Interior Cleaner Protectant (TICP) is the way it goes on. You want to use a fairly deep piled Microfiber cloth to apply it. Pre wet the cloth with distilled water in a spray bottle.
Spray the TICP generously on the interior doors and plastics. It works especially well cleaning off your armrests and control modules for windows, door locks. I would generously spray it on the door panels and work it in, but I would not spray it directly on my speaker grills or into the control buttons, you want to work around that. For those areas, after you do the general door panels, or interior, and then come back and spray on your towel, and then hit the specific areas.
For the front dash, and the LCD screen, I sprayed onto my pre moistened towel, worked it in nicely, then I quickly grabbed another microfiber towel that didn't have a "pile" on it. Almost like those microfiber dishtowels. The reason why is when you go for that quick buff (And just a quick buff, that's all you need) you can and will create some static.. And when you create that static you'll break off peach fuzz off a piled microfiber cloth and it may stick due to the static. So use a microfiber towel with no pile on it and quickly buff it, you don't need much, this product is "hot" and dries fairly quickly, a couple swipes, that's it.
I did get the baby oil scent, and it's reminiscent of that, but not too strong or overdone. A nice fragrance. It comes in a couple other scents.
The final look is very nice, it's not a shine or a heavy sheen, it's in between the OEM flat look (When you first purchase a new car) and a light satin. Just enough sheen to spruce up the interior, but not like a basted turkey that looks greasy or oily. Just right.

works great except on windows
Size: 32 Fl Oz (Pack of 1), Style: Fresh
I bought this to clean everything (dash, door trim and jambs, custom floor mats, infotainment system, center console, windows) but my leather seats and it cleans well and dries quickly without leaving behind that sticky and unnatural shine which is what I prefer. if you like everything having that “wet” look, this isn’t the product for you. my one complaint is that it absolutely does not leave a steak free finish on windows which is fine as I should probably own stock in Sprayway at this point. I was just hoping to carry one less cleaning product but this eliminated 2 so I count that as a win.

Chemical Guys Total Interior Cleaner & Protectant 16oz
Size: 16 Fl Oz (Pack of 1), Style: Fresh
A True All-in-One Interior Cleaner That Delivers
The Chemical Guys Total Interior Cleaner & Protectant has quickly become one of my favorite detailing products. If you’re like me and want one product that can handle multiple surfaces inside your car, this is about as close to perfect as it gets. It’s versatile, effective, and safe to use on just about everything, which makes it a huge time-saver compared to juggling several specialized cleaners.
What stands out most is the versatility. I’ve used this on my dashboard, touchscreen, center console, door panels, leather seats, steering wheel, and even glass with excellent results. It wipes away dust, light dirt, fingerprints, and smudges with ease, and it doesn’t leave behind streaks or any sticky residue. The finish is clean and natural—there’s no over-the-top greasy shine, just a subtle, refreshed look that makes the whole interior feel new again.
Another highlight is the built-in UV protection. Living in a sunny area, I’ve seen dashboards and plastics fade or crack over time. Knowing this cleaner has UV blockers gives me peace of mind that I’m not just cleaning but also protecting the surfaces from long-term damage. That’s a major plus that many other interior cleaners don’t provide in one step.
The scent is another nice touch. It has a fresh, light smell that makes the car feel clean without being overpowering or artificial. Some cleaners leave behind strong chemical odors, but this one is subtle enough that it doesn’t clash with air fresheners or linger too heavily after use.
Application is simple. Spray it directly on the surface or onto a microfiber cloth, wipe, and you’re done. It doesn’t streak screens or glass, which honestly surprised me the first time I used it—I expected at least some hazing, but it left my infotainment screen spotless. It’s also gentle enough that I don’t worry about damaging sensitive areas like electronics or leather.
In terms of performance, I can’t really find any negatives. For deep stains or heavily neglected interiors, you might need more specialized products, but as a general maintenance cleaner, this is exactly what I want. It keeps the whole car interior looking clean and well-maintained without having to carry around a shelf full of different sprays.
Overall, the Chemical Guys Total Interior Cleaner & Protectant is a must-have for anyone serious about keeping their car in great condition. It’s versatile, easy to use, smells pleasant, and adds UV protection on top of cleaning power. I’d recommend it to anyone—from casual car owners who just want a quick wipe-down solution to enthusiasts who detail regularly.
For me, this is a solid 5-star product—an all-in-one solution that lives up to its promise and makes interior detailing faster and easier.

Worth it.
Size: 16 Fl Oz (Pack of 1), Style: Fresh
Love this products. Regret not getting this sooner or even the kit. But super good, and actually smells pretty good no harsh chemical smell. Removed any stained I had with such easy. Which made application easy, just spray on microfiber towel and wipe away. A little expensive but again my fault for not going with the kit.
