$300 sold

Cast aluminum, polished. The stock plenum, due to the slope towards the front, which Nissan designed to clear the stock strut bar on the 350Z, restricts the airflow to the front cylinders. The design raises the front of the plenum as shown in the picture below, allowing more surface area and greater, equalized airflow to all cylinders. Greater airflow equals more power. On average, our plenum produces an increase of 9 hp at the original peak, and a solid 17-20 hp at redline.

This is a solid, one-piece cast aluminum piece, not a reconfigured, welded stock plenum. This plenum will work with both normally aspirated and forced induction (turbo or supercharged) cars, due to the inherent strength of the all aluminum construction. Plus, it is a simple bolt-on modification that anyone can install with basic hand tools, generally in well under one hour.

Kinda interested. What's the big difference between Crawford and motordyne? And could I use a motordyne 5/16th spacer with this? Just makin sure?

crawford plenum
 

motordyne is just a spacer, crawford is the entire plenum. you should be able to run the spacer with this, your only concern is height clearence with the hood. i also do not know the benefit of running both. you also do not run any risk of leaks using the crawford vs. using the motordyne stock plenum combination

This is the same as the motorcycle mrev manifold? Lol

Hopefully you have this in about a week and a half, ill probably get it. Does stock strut bar work with this and a 5/16th spacer? What kinda gains would I expect with this and a spacer? Thanks bro

the stock strut bar will not fit with the crawford plenum. the crawford plenum is already about 2 inches taller than the stock plenum in the front. they make a strut bar that fits it, but you could just run without one. By itself, the crawford plenum gains are about 20whp across the entire powereband. this with the spacer would most likely gain a little more whp but am unsure of this combination. i think most of the people just run the crawford and are happy with the results. when i was n/a this was my mod that gave me the most noticable gains

Is this 300 shipped?

pm'd you

Well your right. I'll buy this when I get paid.

I wouldn't run a plenum spacer in conjuction with this. Also, I wouldn't believe the gains are +20HP at ANY point in the RPM band. Independent dyno's have proven otherwise - however there are definetly solid gains across the board.

This is a great price. The cast V5 is the one to get. I have a non polished version and works well.
