Thanks for the info GMTECH. It might take me a while to digest it all

I like to keep my air intake stock (for now). I dont want any extra noise coming from the engine area.

You mention "I did remove the venturi/restriction tube directly in front of the throttle body and exchanged it with a straight through aluminum tube wrapped with insulation for noise and heat".

Is this something we can do with the OEM filter and filter cover and leave everything else stock looking? Or would we need to replace the OEM filter with a K&N type filter in order to make this work? Would we see any HP gain with OEM filter in place if we remove some of the restrictions? Or dont waste out time unless we go all the way like you did with yours?

Did you "insulate" the tube connecting the air filter to the TB or did you insulate the TB itself or BOTH?

Did this help with intake noise at all?

Thanks.
