Description KP NA Air Filter Kit Instructions Fits Naturally Aspirated models. KP redesigned our original Ultra Flow Intake filter kit, and now offering the newest and greatest! This kit is made from premium 316SS mesh and silicone rubber, ideal for salt water environments! Also Included is the KP pre-filter to help keep out water and debris. The most important part of this kit is the crankcase suction port. This port not only reduces emissions like the factory airbox, but it will pull out all the moisture created inside the engine from combustion. All other kits use breather filters, which do not allow this moisture to escape. This eventually leads to water accumulation in the oil, corroded internals, and rusty valve train parts! For older machines, a valve cover block off kit is required to use this filter kit.
