I was wondering if anyone has had the Z1 intake modification done to their G37. I am considering having it done to mine. Wanted to get some input and feedback first. Thanks!

Yep some people have it, quick search and you'll find everything you need.

 

Yes I have it. You ship them the core, they ship you back a z1 modded manifold. Or you pay up front for it, then when you return your core they reimburse you.

Its a great mod, easy direct replacement bolt-on and you feel the increase in power primarily from upper midrange to redline. A tune will further enhance the power increase.

That's the Z1 intake manifold in a nutshell

 

With a ported lower, ported upper and ported TB's we've tested 10hp plus throughout the power band. I highly doubt you'll feel just an upper.
