I have the same thread on my350z (which is where this originally came from). I have an mrev2 with a Blox 5/16 spacer. Selling them both for $350 shipped. I will get more pics as I take it off the car. Just sold the polished upper plenum so I was finally able to get some pics of it. I verified it as authentic from motordyne when I bought it off my350z forum. I've included the pics so you can see where it was machined I will add front and back pics when I get it out of the car which should be later today. You can PM me and I will send you my info.

 

Is there anything wrong with the MREV2?

Is this for the VQ35DE?

 

Sold.
