i noticed this week my car has had the same filter for 20k at least, would this hinder performance? worst thing is that apparently i need to remove the battery to get into my airbox cos of the screws and my cat 1 goes off cos i have no buzzer shut off key. so i have booked in for a new alarm which is just under 300 quid...ouch. main question tho, would a clogged up sh*tty filter slow me down??
