Thinking about picking up a kit.

 

well it looks like it would work to keep the heat with the turbo instead of it escaping and getting everywhere inside the engine bay, but stupid that they say theres kits for 4,6 and 8 cyl application because its for the TURBO, wtf does cyl have to do with it unless you get wrapping to wrap the headers with. I would get one for the exhaust side of the turbo for sure though those things get HOOOOOOT.

 

Doesnt seem to bad, the only time I see though or similar to thoughs are the shield bags that contain the piece when you hot side explodes. Mainly seen on drag cars running turbos obviously.
