The undisputed king of bolt on power.
A universal manifold modification for use on any VQ35DE engine. When used with or without a spacer or aftermarket upper plenum, this lower plenum will make substantial power gains.
Multiple independent tests show that when used with a 5/16" spacer on the REVUP engine, the combination will add a "minimum" of 15+HP and 18+TQ in the upper midrange. Many independent MREV2 Manifold REVUP tests have dyno'd in excess of 20+HP and 30+TQ in the upper midrange and with high RPM peak power increased by 3-5 HP.
The MREV2 is a prerequisite to the plenum spacer when used on a REVUP engine. No other normally aspirated VQ modification provides as much gain as the MREV2 Manifold!
