TimSri Hi people When servicing my astra 2.2, Is it worth swapping the existing air filter for a K + N but without de-restricting the box? Or shall i just buy a standard air filter? Thanks rallygif
Gazza yea allways good to have a performance filter in there. and to derestict the air box is very easy will take around 10 mins 😃
Matt As Gazza has said, the performance ones are better to have than standard just for the fact they are re-usable, so you don't need to keep buying a new one each service.
