if you want it buy it, look on
ebay you will get almost any type there.
sound is awesome.
i wish i still had my K & N cai.
but i wanted the unichip so i had to settle for VOLANT cai, and it gave me 2 more mile's per gallon go figure.
but i lost it because of the way i drive. i unse my UNICHIP!
as far as the throttle body i have checked and rechecked mine is still clean, when i had my K & N cai on. only thing is i cleaned and oiled mine every 5g's.
it whatever you want. it it's solely for soubd, than in my opinion there is not better than K & N cai.
