666Damian666 Posted September 3, 2015 Share Posted September 3, 2015 K&N are well respected and you would be lucky to see any BHP increase (or at least anything you would actually notice), however you may get a slightly better induction noise Quote Link to comment Share on other sites More sharing options...

richard150 Posted September 3, 2015 Share Posted September 3, 2015 I put a k&n on my st the only thing it a bit more noise on high revs Quote Link to comment Share on other sites More sharing options...
darvvader Posted September 5, 2015 Share Posted September 5, 2015 Yeah there's no real performance gains, but I felt like mine helped the engine run more smoothly and like above, a touch more induction noise at high revs. Sent from my iPad using Ford OC Quote Link to comment Share on other sites More sharing options...
Paramanic Posted September 8, 2015 Share Posted September 8, 2015 Well I have a K&N on my car but also the mountune induction too and better throttle response better noise and car generally feels a little more responsive What people are doing is buying the K&N and porting the box at the bottom or away from the engine and getting same affect as me (need hoses too ) Quote Link to comment Share on other sites More sharing options...
stef123 Posted September 8, 2015 Share Posted September 8, 2015 Remove any dead weight from the car, a few kg removed will be of more use than a fancy air filter. Quote Link to comment Share on other sites More sharing options...
