Bolt on upgrades for performance?

[Gman1950]

I have a 2004 G35 stock with only a Stillen Cold Air I installed. I have been told to stay away from Chips and Oxy Sensors. Any additional ideas besides a new exhaust system? There is a Nissan Performace department at a Dealership near by. Looking for a 3rd opinion.

Thank you,

who told you to avoid ecu mods!? the standard intake, exhaust and ecu have been the most common mods since the z32 hit the market in 90

Agreed. Though a dyno tune is superior to a "one size fits all" ECU tune/chip. If you do go with a dyno tune, be sure to do all the modifications that affect the air flowing into and out of your engine first. That way the person doing your tune can accomodate for, and take full advantage of, all your modifications. (forced induction being the exception, as the ECU needs to be tuned immediately in order to run properly)

A big +1 for the plenum spacer!
