I asked a race car engineer this exact same question before I painted mine black, he said they paint inter-coolers and radiators to match body paint on race cars all the time. He's actually measured the intake temperature himself on painted/un-painted inter-coolers to test it and there was no difference. He told me it's all about air-flow, air-flow, air-flow (yes, he said it 3 times). So, as long as you use a thin coat, i.e. don't get paint clogged up in-between the blades, you can paint it.

 

I painted my intercooler and my engine blew.

 

Whoa thread stopper^^^

 

how do i make my factory FMIC shinny?

 

I was looking to give mine a quick spray but have been persuaded otherwise. Thanks for your words of advice team

 

dam sorry to hear that

 

I was really into this discussion, as it's old and there is NEVER a clear-cut answer. Reading post for post, I eventually came to yours.

I'm sorry, I'm not laughing at your misfortune, just the delivery method of the message. Good luck!

 

hahaha I didnt know you painted your IC was this a different time than the oil filter issue?

 

The two are definitely linked

 

I painted my intercooler and my wheels fell off.
