Upper Plenum Spacer

[Rekinyze]

Guys,

I was thinking of getting a Moterdyne upper plenum spacer (5/16"). Any of you have this spacer or a similar spacer by another company installed? How does it run...any noticeable increase in performance?

Thanks for the help guys!

I have this particular plenum spacer. It was installed along with light weight under drive pulleys. so yes I felt a difference, but it's hard to say from what or how much. supposedly the plenums spacer ads around 10whp in the 03's and 04's

Once I get my taxes back I'll get one. Since I have to pull the intake manifold off to do the plugs. It's supposed to give you 15 crank horse so 10 whp is probably right.

don't expect huge gains form simple mods, nissan did a great job engineering these motors getting as much hp from a measly little 3.5 V6 as ford did with a big old 4.6 V8, thats why the domestic's respond so well to bolt ons

The spacer with mrev2 works wonders on a revup motor. Hp and Tq under the curve increased up to 16whp and 10lbs tq in a lot of areas and it still maintains the peak baseline hp of a revup. I have before and after dynos to prove it, i'll post if anyone wants to see it.

It is actually the one on the motordyne website. Baseline is with a nismo exhaust. It is really a great product. Everything was well packaged, instructions looked great, and Tony from motordyne is a great guy, it is totally worth the price.
