si ive been searching thru the threads and im kinda confused. I have an 03 manual coupe and am thinking about getting a plenum spacer. Is that all i need to buy or do i need something else? and will the power increase be noticeable? thanks

 

You definitely haven't searched too far!

Here's something you should read, I found it typing "spacer for G35" in google.

Wasn't that hard!

ya i know the website but i am just wondering if i should get the mrev 2 or not for an o3 or if the spacer alone will give me a good power increase

 

yes it gives noticable power... I noticed it the most downlow but I have the powerlab spacer....

 

Interesting reading on the subject for you.

I've been doing my own research on the subject too.
