first off... dont buy the V2... its a waste of money.... CAI dont really add that much power...and plus there is no reason to pay that much when u can just buy a generic brand and slap on a k&n filter...

if ur not really into racing... id say spend ur money on suspension...

most after market lightings such as altezzas and halo lights will fog and leak water through... though there are some that wont... a majority of them will...
the only time i ever bought halos was when i installed HID for my EG...i cant recall the brand though but those did fog up after awhile...

again i would say drop ur money on suspension... if u cant go fast on straight beat them on the twist...
