SUPER-FLO KIT is a complete replacement for your OEM filter and cage assembly. Included in the Super-Flo Kit is a super-strong, high-density polymer filter cage with no backfire screen that will allow the maximum amount of air to flow freely to the intake. Included, is a top quality, 2-stage, FLAME RESISTANT, foam air filter. The foam is specially treated to resist flames and sparks and will not hold a flame, so this filter wont burn. We replace that OEM filter cage screw, with the all new No-Toil �Filter Cage Screw Thingy�, that provides maximum holding power with user-friendly ergonomics.
