Boyesen Power Wing Yamaha YZ450F / WR450F

With improved air flow to your machine's carburetor, you will experience a dramatically improved and immediate increase in throttle response, as well as a substantial increase in the low to mid-range torque. Installing the Boyesen Powerwing is very easy and it requires no jetting or fuel changes. Simply install it onto the air box side of your carburetor and feel an immediate difference at the first crack of the throttle with a much stronger pull off the bottom.


  • X-Wing style
  • Increases horsepower and torque in both 2 stroke and 4 stroke machines
  • Aerodynamic design maximizes velocity generation and power gain
  • Wing channel minimizes disturbance at needle jet without affecting jetting curve
  • Precision fit assures perfect alignment and easy installation
