Product Information
Full details
The Twin Air Air Box Cover is an essential maintenance tool for motocross and enduro riders who perform frequent air filter cleanings. It provides the key benefit of protecting your engine's internal components from water and detergent ingress during high-pressure washing. While highly effective at creating a watertight seal, users must be diligent in ensuring the area is completely dry before reinstalling the air filter to prevent moisture-related engine issues.

FAQs
Can I leave the air filter in while using this cover?
No, the Twin Air Air Box Cover is designed specifically to be used only after the air filter has been removed.
Is the mounting screw included?
Yes, each cover comes with the necessary mounting screw for a secure fit.
How do I know if the seal is worn out?
If you notice water or moisture entering the intake area despite the cover being installed correctly, the rubber sealing ring may be cracked or flattened.
Can I use this with any cleaning detergent?
The cover is designed to be chemical-resistant; however, you should always rinse it thoroughly after using harsh degreasers to prolong the life of the rubber seal.
Does this fit all motorcycle brands?
No, this part is model-specific. Please ensure the MPN 723.19.83 is compatible with your specific motorcycle airbox.
Troubleshooting
Water leaking into the airbox during wash
Ensure the rubber sealing ring is free of debris and that the mounting screw is tightened properly to create sufficient pressure.
Cover does not sit flush against the airbox
Verify that you are using the correct cover model for your specific motorcycle make, model, and year, and check for any plastic burs on the airbox rim.

Setup, Compatibility & Care
To install, remove your existing air filter and clean the airbox mounting surface of any large dirt clods. Align the Twin Air cover so the rubber seal sits flush against the airbox opening, then tighten the included mounting screw until firm—do not overtighten, as this may deform the plastic over time. After washing, wipe the interior of the airbox with a clean, lint-free cloth to remove any remaining water. Store the cover in a clean area when not in use. Regularly inspect the rubber sealing ring for cracks or degradation and replace it if the seal is no longer uniform.
