OoooOooOO...Like I said on FA...I LIKE!

 

Have you noticed any significant gains?

 

Same here. Looks great. But would be curious to know your reasons for picking this particular plenum vs others/spacers etc.

 

Thanks jmendoza!!!

HiTech...I have noticed some torque gains. Not much on hp. Hopefully I will be able to feel it more when I install the Injen CAI. I am dynoing my car next weekend so I will be able to see my real gains!

 

I've owned several different aftermarket upper plenums and spacers on my G35 coupe. I have never owned anything APS. I have always wanted one so I got one for the M since it fits.

 

The APS plenum is one of the best ones on the market. You will get gains close (within a few hp) with a MD spacer but you don't get the killer looks.

I have not seen a N/A independent dyno of the Cosworth yet but it may be a little better (for twice the price).

 

Yep...cosworth makes a beautiful upper plenum but its $1k!!!!

 

Ow much is the aps? I can't even find it on the web that has a price tag on it

 

back from the dead... lol
