Kinetix Racing V+ Intake Manifold Plenum

View attachment 174743

that one should be good. similar to a plenum spacer :wink: it wil give you similar gains. gto has a crawford plenum that is similar.

the only gripe I have with this one is the "notch" across the plenum for a 350z strut tower bar. otherwise its should help put in the mid-upper end of the power band.
 
of course, it wont change any of that....

let me dig up a pic for you ...

Kinetix V+ is good, Kinetix SSV is the less liked one. Crawford also makes an upper plenum. Spacer will give you roughly the same result, but with a new upper plenum, you can have the inside smoothed down more.
 
Did a lot of research on this when I was looking to improve aspiration. If you go FI (turbo or supercharger) then I would go with a new upper plenum (APS, Crawford, Kinetix).

I personally went with a spacer - but there are a bunch or brands out there. Most popular is the Motordyne:

But if I had it to do over again, I think I might try this one from Z1 just to be different. I also like the concept of this spacer - angled to improve air to front cylinders since the throttle body is further away. Plus - this one is less expensive.
