Hey Guys,

I got my self an 04 G35 Coupe with very low miles and just slapped on a
Injen CAI, but i am looking for another cheap mod that will give me a lil more
power.

From what i heard the plenum spacer is the direction i should be looking.

My question is what size of spacer should i get and who would be the best
manufacture to go with.

Thanks in advance.

Cheers!

 

motodyne and 5/16 end of thread

 

why would 5/16" be "end of thread"?...

1/2" - thread is open.

 

Ok so what would be the main diffrence or benifit between the 5/16' to the 1/2" spacer?

 

About 3/16"

 

Angled spacer from AAM... thread opens a little more.

The angled design not only allows for you to keep your engine cover on if you install a strut bar at some point, but it also flattens out the top of the plenum, allowing equal air flow to all the intake runners.

 

Typically 5/16" slightly better mid, 1/2" slightly better top end - however there are other ways to get mid... and the difference isn’t so much that either choice cold be considered a bad one.

But by no means is 5/16” the only choice. For ANY reason.

 

There's a cheaper spacer than motordyne's now
