Description Rampage is proud to offer our own High-flow 3.5″ Air Filter that we developed to our dimensions and specifications. The high quality injection molded Polyurethane material thoroughly engages the 4 ply Cotton filtration media and metal reinforcement mesh. This construction is the same as what is found in most large brand name “life-time” filters, but you will notice how much more robust and high quality our flanges are. These are washable, re-usable, and will last for tremendous lengths of time. However as we all know, no filter actually lasts forever which is why we offer these more affordable alternatives to expensive service items.
