TWIN AIR offers this powerflow air filter kit for HONDA CRF 250, CRF 250 RWE, CRF 250 RX ENDURO, CRF 450, CRF 450 RWE 2025-2027. An engine needs air to burn fuel.

Why fit a Powerflow kit?

The benefits:

• More air for the engine: sharper throttle response.
• Dual-layer foam filter that holds dust well.
• Fits in place of the original parts.

Why choose TWIN AIR?

Twin Air invented the dual-layer foam filter in 1972 and is original equipment for more than 30 manufacturers: fine filtration, washable and reusable.

When should you replace this part?

Dust that gets past the filter wears the piston and cylinder very quickly.
