well i ended up getting k&n's for christmas from my parents. which works out great because i wanted them anyway. i'm hoping that it will give it a better rumble, because with my warranty i can't put any type of exhaust which bums me out. just got back from a 1,300 mile trip for christmas and ended up having to change my oil. darn that's a pricey oil change $130.00. but everywhere i went in southern california people just stared and pointed at my crossfire. it was a big hit for my family. which makes the high prices of this car all worth it.
