What kind of performance upgrades can I add under the hood of my 06 Pontiac g6 gt?
Depending on what engine you have, Injen makes a cold air intake for the 3.5L (V6). It is the easiest "bolt on" upgrade that will gain you some hp. It claims a gain of +9.1 HP / +9.7 ft/lbs toque.
Get a performance exhaust system.
Is 9 hp worth $300? Your call.. Beyond that, you may want to look into a performance coil, wire, plug set. You could also go with a "plug in" performance module.
