We stock several replacement and performance drop-in air filters for your BMW. Replacing your intake filter (or filters, depending on vehicle) can improve your BMW's performance immediately.
K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase!
