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 damage?

it really doesnt weigh much and id rather have that insulation between my manifold and the hood especially since the underside has no insulation.

NAAAAH , your wrong, it keeps concentrated engine heat off the hood and lowers noise.

You can prove this with a laser thermal reader, also you need the heat in the right places for optimal engine performance.

Can I make an omelette this summer when it 95+ outside on your hood.

While it may help with NVH (not sure how much), it also adds heat soak which is not a good thing in my book. Not saying it would matter outside of the track or that anybody even tracks these cars...

Decreases warm up time possibly?

On some older cars you can see a faint outline of the engine block on the hood. Most likely from heat. Engine covers most likely prevent that and make the engine look way cleaner.

It's certainly heat insulation and possibly a fire suppressant as well (maybe). The engine's a little louder without it, I've been keeping mine on since realizing how hot the hood gets without it.

It is there so they dont have to insulate the whole bottom of the hood. and to cover everything as thats what car companies do now.

Taking it off serves no purpose in any kind of street driven car.

Seeing as our hood doesn't have heat insulation on it to protect the paint from engine heat, this is the only barrier between the engine and the hood. I would NOT take that engine cover off unless I put some other kind of heat shield under the hood.
