I just picked up my 06 350z a week and a half ago so im new to the VQ35 family. Ive search alot of posts where ppl say the nismo/injen/aem intakes suck and lose hp. what about combined with spacers. Im looking for the best performance gains not sound or looks.. help me out plz....

 

.

 

get a k&n filter panel you will be happy...short of upgrading to a sealed short ram intake like the one arc makes the panel is a good choice...

 

popcharger and AAM/MD spacer are the best combination

 

Im definately going with the JWT popcharger, most proven hp gain, it was even written in a few magizines. Ive read some good things about the AAM spacer, but not to much about skunk2 spacer or others. Whats the signifigance of a angled or non angled spacer and size differences?

 

Concerning spacers, check the Sport Z magazine plenum vs plenum spacer shootout. I think the choice is pretty clear.

 

thanks man ill check it out. 1 more question, does the JWT popcharger simply take the place of the OEM airfilter box and use the OEM tube or does it come with a different tube?

 

It replaces the airbox. you use the OEM tube.

 

ok cool thnx 4 the info guys

 

i have the 5/16 iso thermal spacer, it bumped me up 10whp. good stuff!!!

 

i have the jwt popcharger, and a motordyne 5/16 spacer and its awesome.
the motordyne spacer is what davidv was referring to in the sport Z issue. the 1/2 spacer showed the most gains up top, but the 5/16 still allows u to use ur stock strut bar.

 

It's proven, many CAI long tube intakes lose hp.
