I have a 2006 z and i'm still very new to the 350 thing. So with that sad I have some questions, I want to add some things to my car and i've seen the MREV and MREV+ and didn't know the difference and also wanted to add a plenum and the also saw there was an upper plenum, is there a difference?

 

Hi kj98r05,

For the most gains in area under the curve, I recommend the MREV2 with a 5/16" Iso Thermal plenum spacer.

Dyno testing shows that the MREV produced more area under the curve when a 5/16" plenum spacer was used. Even more than the 1/2" spacer.

The 5/16" plenum spacer also allows you to keep your stock strut bar. It will also be very stealth. (if stealth is what you are looking for)
