helloo... i have a Audi A3 1.6 2006 8P modell... when i take the airbox cover off the sound of the car becomes amazing... i was wondering will it damage the engine or any other part of the car if i keep the cover off???

thankkss

its best left on because you could get dust/dirt on the airflow sensor or even worse into the throttle body, fit a K&N filter

if i fit a K&N filter... do i still have to have the cover on ??? or will it just have the same sound with the cover on?

thanks
omid.

you would still need the cover on if you fit a flat panel K&N but you could mod it with a cone filter cold air induction kit and then you will keep the noise
