Welcome to the site, it's a great place to learn about our cars.

 

what 4D05G35 said is your best bet, thats where I've gotten most of my ideas (and dreams mod ideas) from. other than that just look around the forums at threads with what people have done/are doing that should get you off to a good start (beware the mod bug too)

 

Motordyne 5/16" or 1/2" spacer, get the Aramid gasket to help with the heatsoak too, a cat-back, and that's a good start!

IMO, the air intake is just a sound mod, if not a mod that loses power. Short rams are the WORST!

 

what does the plenum spacer all do exactly??

this website has all the plenum spacer answers you need!

 

So far this is the best mod I've done. 5/16 IMO is the best for all around daily driver.
Air intake mods on our cars only benefit from higher flowing filters. Power/fuel economy is negotiable.
