Hey all! Just picked up an '06 S Sport 5M with 67,xxx, bone stock. What are you guys using for cold air intakes? I was thinking of buying a cheap intake off of ebay for the tube and then putting a K&N filter on the end of it...or would I be better off getting the full K&N set-up? I'd like a set-up that has a full solid tube going to the throttle body. I noticed the Injen intake says its only applicable to the Auto trans cars. Can they be made to work on manuals? Also, have you guys noticed an increase in fuel efficiency after installing a cai? Thanks!
