Default Is the LS3 padding/cover necessary?

I swapped LS3 heads and LS3 intake into my C5 corvette. Found out the LS3 intake is just to tall with the padding/cover on it. It fits just fine without it though.







I have maybe the thickness of a pencil in clearance with the padding/cover gone. It's so tight it wouldn't even fit with just the plastic cover and no padding.


What does that padding do? Is it just to quiet the engine down?

i think it's for sound deadening. mine interfered with the holley tb. i pulled it, it looks just as nice, if not nicer, plus i shed a pound or two.

what'd you do to connect the ls3 map sensor? doesn't it have a different pinout than the earlier ones?

Just got back from the GM dealer, I'm doing the same. Picked up a pigtail with the new connector to splice in.


I could always just cut off the rear portion of the pad/cover and that would work too.
