Outerwears Pre-Filter, 4 1/2" x 6" Black (Fits Walker 6" Air Filter

Outerwears Prefilters are designed to deflect damaging debris as small as .005" away from air filters. By protecting your air filter with Outerwears you extend the life of your air filter between cleanings. Outerwears Prefilters are made of puncture resistant polyester mesh which is shatterproof below freezing and resistant to heat up to 450º. The material is constructed with reinforced industrial grade thread and welded at the seams for strength, yet still maintains the elasticity to return to the original position after an impact.
