Plastic Engine Cover - what is the point?
What is the point of this plastic engine cover that Infiniti puits over our engines. I toook it off and it looked a lot cooler in my opinion. Does anyone know if it is just to make the engine look neater? I would like to leave it off but i dont know if it has a mechanical purpose, like heat sheild or something. Just though I would ask and see what you guys think. I did a search but I didnt find anything.

The top cover is just dressup, and leaving it off will definitely help cooling.-----now where the h*ll did I leave my glasses.....

I like the darn thing. I modified mine to fit my Crawford plenum. I think it finishes off the engine nicely.
