Spark 2

Has anyone removed the foam insulation that is mounted under the

FRC?

What if any were the results?

Cooler running?

More engine noise?

What are your thoughts and or opinions?

I removed both the FRC's on my '12 LS3 & the foam-insulated intake manifold cover too.

The FRC's come off easily, & the intake cover took @ 30 mins because I wanted to retorque the 4 bolts that I loosened correctly. If you loosen/retorque all of the intake manifold bolts, there's a specific sequence to follow.

I really didn't notice much, if any, extra noise, I just didn't like the plastic things & wanted the engine to get more air circulation as well.
