258 Air Intake Temp

I am replacing my exhaust manifold and figured it would be a perfect time to get the air intake cleaned up and either powder coated or ceramic coated.

I have already done the ceramic to the exhaust manifold because of the temp issue.

The question is whether or not the air intake gets too hot for the powder coating. Supposedly powder coating starts to break down / melt / burn at continous temps above 400 degrees. That's according to the powder coating place I am using....

What do you guys think? And thanks for the help!

I doubt if the Intake gets much above the water temp, it has coolant running through it, bypass and the heater hose in the rear

!980 CJ can still be running the cast Iron manifolds which are heated with the exhaust gasses blowing on the intake under the carb. It can get hot in that one spot. How hot I don't know.

I have powder coated my entire engine, including the intake manifold and the heat has no effect on it. I even powder coated the cast iron exhaust manifold with a special silicone powder meant for high heat and it is holding up well. The engine has about 6000 miles on it since its been powdered and still looks as good as the day it was done.
