  1. Deleted engine cover, serves a function or just aeasthetic?

    I took off my engine cover, does the cover serve a functional purpose (protecting hood/surrounding components from heat or is it purely aesthetic?) Reason I ask is because I see this heat protection/padding on the underside of the cover...or is this just to protect the cover itself from heat...
