K&N 04-09 Yamaha YFZ450 Carb Aircharger Performance Intake

K&N's easy to install air intake systems replace the restrictive factory air filter and air intake housing allowing for virtually unrestricted air flow and delivers a guaranteed power gain.

The K&N 63-1123 AirCharger air intake system replaces the restrictive factory air filter and air intake housing in some Yamaha YFZ450 models. K&N 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 than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 63-1123 air intake comes with a black rubber 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 heat shield accommodates a replacement silicone crank case vent hose and supplied CCV filter. The oversized cone shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and some wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
