The installation of this product was a breeze. I am impressed with the performance that the plenum gives the Z especially at higher RPMs. The only other "go fast" mod that I have on my car is an Injen CAI. I noticed it the most when running for top speed. Getting up to 140 is alot easier than before. It also adds to the sound of the car by amplifying engine noise under full throttle. The only downside to this mod is that the engine cover sits kind of funny on the new plenum. I will deal with that any day for the improvements that this plenum brought. I can't wait to see how it does when I get my Kinetix cats and Injen exhaust installed!!

 

sweet! How much did you get it for?

 

I don't remember, but I bought it brand new from a private seller on this forum for a little cheaper than Kinetix sells them for.
