Would having an intake manifold sent out to be hot coated have any benefits, similiar to how headers get hot coated? I know you do that to headers to keep engine bay heat down, but if you insulate an intake and the IM, that would aid in keeping the air cooler when it enters your engine. Am i right in thinking this or out of my mind? Shifty.gif nuts2.gif

 

No.

 

To be more loquacious: the benefits would be infinitesimal. The amount of heat your intake air charge picks up from the engine bay air through the body of the intake manifold is probably pretty tiny, especially compared to the heat it picks up from the studs holding the manifold to the head (not to mention the head itself, if you don't have a thermal break (phenolic spacer) between the head and manifold.

 

Not sure what hot coating is, but ceramic coating will help, especially if you combine it with phenolic spacers.

A ton? No, but you will get cooler temps to the engine, and much less heat 'soak' effect.

 

BTW, I had my airram ceramic coated, it wasn't that expensive, looked good, and kept the temps lower.

 

If you do ceramic coat the IM, make sure you also have a phenolic spacer otherwise you'll probably hold more heat in to the IM than you're keeping out.

 

+1 to that, right on the damned money.
