Power Intake Tube 2017-23 EXC -F /XCFW / FE-S / FE 450 / 500 / 501
The 2017-22 EXC's XCFW / FE-S and FE's have a reed assembly from the 2-Strokes, in the intake tract. Purpose is to reduce intake noise but it also kills power. Plus the reeds could break and lodge in your throttle plate and cause your throttle not to close or sick into your intake valve and cause your engine to blow.
Just Removing your reeds isn't enough as the large rectangular hole kills the low end air velocity. This lowers throttle response.
Get 2-3 HP and throttle response back with the Power Intake Tube. Requires you to increase Fuel either with our Programmer or 02 delete/booster plug kit
