Since ive got my 350Z 2 days ago, my homies keep telling me about a plenum spacer. Ive heard it helps gain horsepower, but i dont even know how it works!?
If its a good buy, what size would be best for my 2006 Z!?

 

Depends on if you are planning to use the stock strut bar or use something different. Stock strut bar 5/16ths with most other strut bars 1/2 inch and go with the thermal offering from MotoDyne, also Intense is selling a new in house product at much better pricing. Good luck either way, you can search there are literally 100's of threads on the topic here.

ahahaha. but seriously, id search..the mrev2 lower plenum and the spacer. both good gains for the 06. check it out!

 

Check IP and BAN!

 

Fail @ lolz?

 

your homies should have told you to search first before starting a thread on something there are a million threads on already

 

Plenum spacer? Never heard of it.

 

I have a question. For some reason the bolts in the center come loose after I installed the plenum spacer. I torqued everything down to specs. I had to reuse my stock bolts and I used some washers with rubber on one side. You think the rubber is preventing the proper closure or seal

 

I don’t have great concern about the center bolts. But if you want use a little Loktite.

 

Um... are the stock bolts even long enough for the spacer? All mine were way shorter than the supplied bolts. At least they were with my 5/16" MD spacer.

 

use the 5/16 spacer and buy an mrev2 if youre 6sp

 

 

i dont know how i feel about it-just the upper seems like it loses that smooth pull all the way up,and it causes the dash to vibrate- just get both parts from motordyne do a cb with tp,headers,k&n drop in,and then get some kind of tune,other wise i dont think its really worth doing first-but thats mo.

 

a tune will always bring the best out of any mod
