Powder coating intake and exhaust manifolds

So motor is in shop and i wanna make the engine look all good for alittle atleast so im thinking of dropping the intake and exhaust manifolds off to get powder coated. I know the exhaust needs to be ceramic coated but what about the intake can i just have it powder coated or does it get to hot for that? Thanks

Probably too hot unless someone is offering a specially made coating.

There are shops that specialize in this sort of thing for hot rodders, if it means that much to you, check them out.

You can use normal powder on the intake.

200k miles later its still there. Its a black wrinkle finish

If your intake get too hot for powder coating you have bigger problems

The exhaust on the other hand will not stand up to powder, as you noted.

If you are going that far, a header is a better upgrade and can be purchased pre coated, make more power and improve MPG a little.

The standard powdercoat will hold up to about 400 degrees. I have done many intakes,Valve covers,oil pans ect. and had no problems. Exaust, I have had them stay nice (with high temp exaust/BBQ) for awhile but not permanent.

If you do the intake with a dark color you will be fine. Anything bright or white will start to discolor around the points close to the exhaust. Radiant heat from the exhaust will exceed 600 F.

Find a shop that will ceramic coat your exhaust manifold. It might be cheaper to buy a header that is already ceramic coated.

Jet-Hot for the exhaust manifold. Silver or black.

If your ceramic-coated exhaust manifold gets wet when it is hot the coating will crack and rust will form underneath.

Geez, I love the way that looks; I wish my Jeep was worthy of something like that!

Yup. Check out the exhaust manifolds on any stock 6 cylinder E-Type Jag that is street driven. Ceramic coated right underneath hood louvers.

Well, everyone loves a good deeming.
Here's my take on this- The engine is already out and at the shop. There is no issue with powdering the intake, it will hold up just fine. You can even do it yourself, it's very easy. I can give some tips and lead you to some applicable reading if you like. Keep in mind that powder shops don't care for doing onsies and twosies. There's no money in it for them. The more parts you bring the better the price you will get because it's not cheap to fire an oven... They may even hold your part for a day or two so that they can cure a larger batch at once, of course this depends on how busy the shop is. The OP and others that have offered opinions are correct in their summation that the exhaust needs to be of a more durable coating like a ceramic. I'm not sure that I would bother with paying to have the stock crack prone exhaust manifold ceramic coated. You may be better off paying just a bit more for a decent header that will provide additional HP gains as well. Win Win, right? The engine is out, nows the time to do the things you will regret not having done later. Good luck with your build.
