Hey everyone, I just got done installing a Altered Atmosphere plenum spacer on F1James' 350z. He won it at the raffle at Z DAYZ. Overall a very clean, quick and simple install with good instructions and all of the parts needed. The whole thing took only an hour, with the work being done at a leisurely pace. Suggestion, allow the car to cool for several hours before attempting, because the plenum gets very hot from the ambient engine heat.

I took some pictures, and if you ever wondered what it looked like inside the plenum, that is the passenger side. The driver side is the same. The other 2 are of the plenum installed.

 

nice job.

 

any performance gains? anything sheer notice in higher rpms or lower?

 

nice pics and clean install, did you notice any differences right away?
