need some info

[OzzUm]

My ol lady just got an 08 grand prix and was wondering where is the best place to start to get a little more pep out of it. Any info would be great.

Thanks

well you can always get a K&N air intake system. its not going to get you alot of extra power, but it will do alittle bit. Plus having this system will get you prepared for anything else you might be thinking about. The more air you get to your engine the better. I put this on mine and i felt alittle extra power in the acceleration part of things, helped gas mileage alittle, not much, but it helped.

you could also get a new exhaust system.

catbacks don't do any perfomance gains for these cars and K&N's cai is worthless. The only time you need an aftermarket catback is if you are over the 300hp mark, even so there are many 12 sec GP's still on the stock catback. A tuned pcm will benifit you the most. IMO these are the best ones out there

INTENSE-Racing.com - G8, Grand Prix, Bonneville, Regal, L67 3800 Supercharged Performance Products. <pcm is unlocked in case you need to reflash it later.

A Plog from www.zzperformance.com would help alot along with a 180* t-stat and a CAI such as wizard. You could stick with the stock dp if you want their isn't many gains there, since you don't have a u-bend.

p.s a cai will hurt your gas mileage, not help as stated above.
