No-Toil BIG AIR Hi-Performance Foam Air Filters are made from the highest quality reticulated, flame-retardant foam that combines the best air flow characteristics with dirt stopping capabilities. The open cell structure of the foam is proven to breath more air for more horsepower while stopping dirt from making it's way to your engine.  The reticulated foam has way more surface area to stop way more dirt and still deliver your required air flow. The dirt load ratio surpases all other mediums of air filtration.  The foam element is supported by the No-Toil composite filter frame that is specially designed to allow maxixum amounts of air flow with limited obstruction and rounded surfaces.  Treat your BIG AIR filter element with No-Toil Evolution Filter Oil and benefit from the Micro Flo technology which makes the oil the least air-resistent oil on the market.  So, air will flow through the foam faster than any other brand air filter oil.  Slick as snot, yet redonkulously sticky.  BIG AIR foam filters: allows more air, stops more dirt. Available in 3, 4, and 5 inch High models.
