RFX Air Box Wash Cover (White) FXAW1000355ST - Honda CRF250R 2022-2024 / CRF450R 2021-2024

Product Description

The RFX Air Box Wash Cover mounts directly in place of your foam air filter to protect your intake tract during routine maintenance and pressure washing. Specifically molded for late-model Honda CRF250R and CRF450R machines, this essential tool seals the intake opening so you can wash out trapped roost, mud, and grime inside the airbox without risking engine contamination.

Constructed from rigid ABS plastic, this wash plate forms a tight waterproof seal against the airboot sealing flange. It stops water, wash detergents, and loose grit from entering the intake tract, keeping the throttle body and intake valves protected so you can clean thoroughly after every ride.

Frequently Asked Questions

Q: How does this wash cover attach inside the airbox?
A: It attaches directly to the stock air filter cage mounting point, clamping down against the intake boot flange for a tight seal.

Q: Can I spray water directly at this cover while washing?
A: Yes. It is designed specifically to block high-pressure spray, water runoff, and cleaning detergents from entering the intake.

Q: Should I dry the airbox before removing the cover?
A: Yes. Always wipe down and dry the inside of the airbox housing before unbolting the wash cover to keep stray moisture from entering the intake tract.

Expert Pro-Tip: After pressure washing your bike, spray a light coat of contact cleaner around the perimeter of the wash cover and wipe it down with a clean lint-free rag before removing it. This removes standing water and loose grit from the sealing flange so nothing drops into the clean intake tract when installing your fresh filter.
