Performance Air Intake System
The K&N 57-1124 FIPK air intake system replaces the restrictive factory air filter and air intake housing in specific Kawasaki KFX450R models. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air with less effort than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. This air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The air intake system accommodates the factory air temperature sensor and crank case vent hose. The oversized cone shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from excessive moisture and dust. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a couple of screwdrivers, a ratchet set, needle nose pliers and several wrenches.
