i dont know if you have a nopi close by, but thats where you can go or just check out
www.nopi.com or go straight to
www.nopionline.com. get the DC cold air extension for around $50 and it will fit just right onto your ractive. but you may have to do a little cutting on the ractive intake.
i think injen cold air extensions may fit too, but they're more expensive. go with dc.
