A universal manifold modification for use on any VQ35-DE engine. When used with or without a spacer or aftermarket upper plenum, this lower plenum will make substantial power gains.
Multiple independent test show 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 MREV 2 Manifold REVUP tests have dynod in excess of 20HP 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 MREV 2 Manifold!
Note: A $100 core buyback is available for those of you with non-revup lower collectors. Contact us for more information.

Yeppers, that's what it is. Someone found out that if you put an 04' lower plenum on an 05' "Rev-up" motor, you got more HP in the mid to upper ranges. Motordyne did a little flowbench testing and came up with some mods that almost doubled the out put. The least you get is 10 the most is over 14 (if I remember right) and there are dynos on here to prove it.

This thread has gotten so many responses and I haven't even got the spacers yet. I'm hoping they will come in by mid week and I've got a guy who will do the install for $45.

Most people install it themselves.
Some people will tell you that you don't need a torque wrench, but you really should use one. I went to Harbor Freight and picked up a cheap one (enough to keep me out of trouble) that measures in Inch Pounds for $20.
Its worth it to keep from snapping off a bolt and having to deal with all that mess.

I did it with a buddy that knew less than me.
Although I do have access to a shop and associated tools, lift, etc. I am not terribly mechanically inclined.
No problems during or since. It took a couple of hours but I was pretty meticulous.

man, is the spacer really that noticeable?? this is like the last mod i was going to do and i've been back and forth for the longest time now. reading through this thread got me thinking of purchasing it again.
i just hear so many peeps talking about how the rpms drop and jump around, engine lights coming on, etc. makes me wary.

yeah, all the evidence points to "yes." lol dammit, might have to do it.
