Used exclusively on our dirt oval karts. These pre-filters do the job while maintaining performance! Specifically designed Outer wear for Walker Performance Filtration. These white outerwear help distinguish the good from the bad. They let you see when the element needs to be cleaned and replaced much sooner than the colored versions. We make them baggy on the filters so the oils from the media don’t create any restrictions on the air filter. Get the best in filtration and get #WalkerWinning!
