Has anyone removed their under hood insulation?

Was there more engine noise heard inside the cab?

Did the engine heat damage the paint on the hood?

Did the engine run any cooler?

Why do they even put it there at all, to protect the hood paint or for noise suppression?

 

Noise suppression on higher end models. I doubt you'll notice it's missing.

 

Mine doesn't have it and I have hood vents. The wifes has it. Can't tell a difference

 

Its there to protect the hood,, iffy.... but mostly for noise control..

 

I have read several posts on this. It appears as if on the earlier modles (pre 1997),the underhood insulation is actually material that when on fire will melt and drip down onto the engine to put out the fire. Good idea but did not seem to work all that well. JB

 

Same here but I have no hood vents on mine. Wife's has the insulation. I can't tell the difference.

 

None of my XJ ever had it.
