Yesterday i got a K&N and i removed my air silencer, but I couldn't figure out how to remove the whole airbox without having too much extra space on the filter so that unfiltered air could get in. What have you guys done to take out the whole air box? because I really don't want to buy a CAI as i hear they don't do anything, but i do want an open air filter s i can get that growl out of my motor
