DANG60 0 Posted June 15, 2010 what sort of air filter are you using? Quote Share this post Link to post Share on other sites
mimjed 0 Posted June 15, 2010 dont think you can completely get rid of it to be honest, unless you remove the charger. the compressed air will still be chucked out the bottom of the throttle body with a boost reurn pipe fitted. Quote Share this post Link to post Share on other sites
