Real tech discussion on design, fabrication, testing, development of custom or adapted parts for Pontiac Fieros. Not questions about the power a CAI will give.
I assume you're talking about the stock motor, but I removed the stock heat shield from my 3.4 DOHC V6's crossover pipe and replaced it with header wrap. It seems to have helped a lot. The engine bay doesn't feel quite as hot after a long drive.
I don't use header wrap on the headers themselves but on my setup I have the crossover wrapped and the downpipe as well. I am using a turbo blanket on the exh side too.
It brought down temps a lot.
Also using this in conjunction with the stock heat shields.
first thing i did after my motor came out of the car was cut off all the tin heatshields except the one around the coil. manifolds and y-pipe got wrapped in black header tape and sealed with silicone sealer. they look awesome and are a snap to clean. the silicone even covered up my rusty ass egr valve nicely.
