MODS for HP and / or better MPG

[ocho]

I've been thiking that increasing air intake and a plenum spacer aside from awakening a few ponies in our G 35's it might help in gas consumption as well ( I mean less of course) in normal driving. Anyone care to coment?

Intake mods will help but they also will richen the a/f mix. put on an exhaust to go with and you'll be better

As for better MPG....i have notice it, but only when i'm driving highway for longer trips.

It will....and it won't. If you can lay off the throttle, intake and exhaust mods will give you better MPG. However, the sound is very pleasant, and you'll rev the engine more. So it's up to you!

Possibly the intake and the exhaust.
