Not worth the minimal HP gain, and possible overheating and charging problems you might run into.

Steeda, or March are the ones I'd go for. I've read/heard of gains as low as 7hp and has high as 15hp. Personally, I went with March. They just came out with a new set #1190 which are made specificallyl for the '02-'03 models. I've heard of possible overheating, but it's not very common from my experience. And if that does occur, I would wonder if a new thermostat might help (I really don't know). IMO $160 is not a lot for say 12hp, cuz every little bit counts.

Yea....i recently installed the underdrive pullies and it was like a totally different car after that. 10hp is 10hp. And it goes right to the wheels. Yer engine seems to spool up alot faster also. Under-drives are definately a must imo. If I could do it again, I would start with u/d pullies and 4.10s as my first two purchases. That CAI is a buncha hogwash and only shows like 4hp to the rear.</P>


Ive only had the pullies about a week. So far nothing has changed with the cars temp and everything else seems to work normal. Even the lights dont dim.</P>

I've had my steeda pullies on for a about a year and am starting to experience some low alternator output. It seems to charge alright, as I've never had the dead battery. Just low voltimeter readings on the dash. The pullies make the difference and are worth the dimmed headlights... lol... if they really bother you, get a high output alternator... check them out at www.racingsuperstore.com

There's where I got a lot of my stuff.
