So I installed my plenum spacer today. Now I gotta be honest, I really didn't believe all the hype over this thing to begin with. I got the ISO thermal 5/16 for $200 so I figured for that price the risk could be worth the reward. Oh and was it ever! I am a believer now. The throttle response is more crisp, feels more instant. The car now sounds throatier, n my butt dyno says its got more HP, j/k. It does feel a tad quicker tho. I'm so glad I did it n its so ez to install! I am now a believer. Thnx MD!

Not to thread jack but does anybody know if the G35 5/16th copper iso thermal is the same for the 350z?

well if you have the same year motor they should be the same because the g35 and 350z have the same motor. I would just make sure that it still fits under the Z strut bar.

If you get the Motordyne spacer, it will have EVERYTHING u need, down to the last washer for the strut tower bar. I was really impressed w/ the kit. The Z spacer should work for the G as well, same engine. It's definitely worth the $, the HP per dollar ratio alone makes it worthwhile.

i agree. I just installed the MD 5/16 iso thermal on mine last week and i feel like its easier to rev the engine. I noticed that it does make the exhaust sound alittle louder and throatier. I feel like the car has gained alittle in HP.
