Pair with the  for maximum airflow and power!

The best filter in the world can’t do its job if there are leaks in the seal of the airbox. That’s why Twin Air provides a complete line of products to ensure a leak-proof, fool proof fit. Twin Air’s PowerFlow kit comes with a rigid, lightweight, billet aluminum cage that provides a tight seal to the airbox and replaces your flimsy plastic stock cage. 

4 – STROKES: Twin Air PowerFlow kit for 4-Stroke models: Replace your air-restricting stock backfire screen with our New PowerFlow kit. The kit includes a rigid, lightweight, billet aluminum cage with a special backfire-resistant layer of foam laminated to the inside of the filter.

• The 2024 KX 450/X OE airbox and filter design is lacking in sealing and air flow
• The stock cassette style cage/filter does not seal very well and is susceptible to sucking dirt into the intake/engine which can cause catastrophic engine damage
• The Twin Air PowerFlow kit greatly improves the filter sealing issue that the OEM filter/cage has, while increasing the air flow by replacing the flat restrictive stock filter design with a larger domed style filter to increase air flow
• The Twin Air PowerFlow kit includes a Glass Fiber Composite Cage, Base plate, and Pre-Oiled Air Filter (FR).
• This kit replaces the complete OEM filter system
