    Ceramic coating

    I was just wondering if anyone has Ceramic coated an inter cooler? I know it helps keep exhaust systems cooler. But would it help an inter cooler?

    The whole purpose of an inter cooler is a hear exchanger, ceramic coating would be a step in the wrong direction.

    It would keep an intercooler hotter, which defeats the whole purpose of it. Intercoolers help lower the intake air temperatures after intake air is compressed by the turbo. Colder air is more dense, and since your engine is just an air pump, it is able to achieve a higher mass flow rate as air density increases. (There's a lot more to it than that, but that's the basics).

    Ceramic coatings do not aid heat transfer, they inhibit it. They "keep exhaust systems cooler" in the sense that less heat is allowed to transfer through the exhaust walls and radiate into the engine bay, which means in turn the exhaust gases within the exhaust are hotter.

    tl;dr: ceramic coatings are great for keeping heat in, which is the exact opposite of what an intercooler is supposed to do.

    I have, but only because I'm an engine bay queen. As said, no, it doesn't help prevent heat soak at all, but it doesn't really hurt it either....unless you apply enough coats to decrease air flow through the fins of course.

    Definitely NOT..... In an exhaust or turbo component you want to retain the heat within the components to be expedited out the exhaust. You want the opposite In an inter cooler. You want to be able to shed heat quickly. The coating you want for this application is aptly named a "heat dissipating coating". The advantage of these types of coatings is that they are capable of shedding heat faster & more efficiently than the raw substrate could.
