hey whats up just getting ready to buy a plenum spacer and have been wondering whats the ups and downs with different sizes and whats a good brand?

 

go motordyne engineering...

5/16 for across the powerband increase.

1/2 for top end.

 

I have been wondering the same stuff. I have done alot of reading up on these too. Have you checked out G35parts.com or Conceptzperformance.com? both sites have a decient summary on the the plenum spacers...hope I could help

 

Do you have a revup or non-revup engine?

Revup works best with MREV2 & 5/16 spacer.
Non-revup I think works best with just the 1/2 spacer.

some reason i want 1/2" spacer

 

yeah im thinking im going to go 5/16 on it. and ive been looking at motordyne and skunk 2 is there really a big difference

 

Then there's the Z1 3/8" spacer to confuse you guys

 

I'm getting my MREV2 and 5/16" spacer this week. Should be installed by next weekend.
I'll do a review after it's installed to let you guys know.
Going onto a 6MT 06' coupe.

 

But one thing I was looking at as I was also interested is that if you install the 1/2" you can't put a front strut brace or is that only Stillen?

 

Can someone clarify that the 1/2" spacer is a better option for the 03/04 Gs...

Tony is the Motordyne Guru

 

People say to use search, but i sometimes do and still cant find an answer, motordyne site says the coupe can only take the 5/16" plenum spacer, i would call tony but its b4 brunch.

 

to further complicate things AAM makes an angled spacer (variable height) to help flow to the front cylinders -- that's the one I use.
