I have a question...Does it matter what size plenum spacer I use for my 05 g35? And if so, what brand because I have heard that Skunk2 has a spacer that works pretty well 5/8". Let me know what you think..I gladly appreciate it.

 

if you are a 6mt, your best bet is mrev2 with the 5/16" spacer. if you're 5at, then the 5/16" or 1/2" spacer alone will suffice.

if you opt for the spacer only though, then the skunk2 spacer is way too big (imo). stick with motordyne's 5/16" or 1/2" spacer.

 

^+1. Stick with 5/16 or 1/2".

 

^+2. Just remember that the plenum cover won't fit if you go above 5/16".

 

Thanks...anyone else responds I appreciate it. And is there any other parts that I need to tune or adjust upon installing? thanks guys!

 

Motordyne 5/16. I have one sitting at home until I can get around to installing it. The skunk, like others have said, is too big, and it will actually take away power in the lower rpms and only ad some in the extreme high rpms. The motordyne 5/16 is the best spacer for overall linear power.

 

Mine fits perfect, no touching or rubbing. I'm not sure abour the coupes though.

 

I'd opt for the Motordyne plenum spacer product.

 

Congrats!!

This is one of those rare times where size does matter ...but in this case...smaller is better!DOMO
