Engine covers

[Jay C]

Hey guys I just had a quick question are the covers on the 7M-GTE there for aesthetics or for protection? Reason I am asking is that I have been seeing a lot of pics with them off and not sure if it makes a difference operationally or not (or if they are just being removed for the pics). This goes for the top cover (that covers the spark plugs) and cam cover specifically. I also wanted to know generally the same things about the turbo heat insulator shroud (as most pictures do not show one) I would think it would help the turbo run better but I could be way off. Thanks for sharing your thoughts on this.

Coil pack cover is for looks. And the heat shield is there so you dont burn yourself and keep the heat contained.

-Coil pack cover is for looks.
-Timing cover is for protection.
-Heat sheild are for protection of everything else outside of the exhaust. Previous owner of my car left the front one off the manifold and the wires in there crumbled when I went to remove them...

I never get to answer threads before others....lol. I guess I am not fast enough to find the thread.

^^^ At least you came to look.

Also, the heat shields of the exhaust area help save the paint on the hood.
The engine undercover is supposed to help concentrate the cool air through the radiator, useful in hotter areas (ie Arizona)
