Intake manifold: Powder coat, or ceramic coat?

**artemis** · 8-6-09, 14:29

I called up a local coating place today asking how much it would approx. cost to powder coat my straight neck mani. She sorta goes quiet for a second and asks "You want to POWDER coat it? I've never heard of anyone doing that to an intake manifold before. We have always ceramic coated intake manifolds" WTF? I thought everyone here with a coated IM had it powder coated, not ceramic.

This is her argument. Powder coating can only withstand temperatures of up to 400-500° F, while ceramic can withstand 1200-2000° F. I know the IM gets hot but... does it really get hotter than 400°F?

This [shizzle] is confusing me now.

did you tell her it was an intake manifold? she was definatly confused

Yeah, she probably thought you were talking about the exhaust manifold.

Yeah and she is a girl so there is a large possibility she is retarded. :P

I am pretty sure I said intake... multiple times.

Either way... this bitch is getting powder coated.. I'll post pics when it is done!!

imo its a waste of money to even have it powder coated.. unless its done for super cheap.

you saw the pictures of my manifold.. and i spent like 12$ on the paint for that haha... Advanced auto has a ceramic spray paint.. i think its rustoleum.

Ceramic coating is good at deflecting heat, so the manifold stays cooler under excessive engine temps, that's why they recommend ceramic for intake manifolds. However, simple paint or powder coat should work for your application. In my case I just painted my old one. Worked great for years.

Seriously man, paint will do you fine and costs a tenth or less

^Yep, unless she's a show car which you wash the engine every few days, I wouldn't worry about it. VHT high temp paints work great for these cases. Caliper paint would be more then enough heat protection.
