Full details
The Twin Air Powerflow Kit is designed for motocross and off-road riders looking to maximize engine performance by eliminating airbox restrictions. By replacing the stock air cage with a precision-engineered aluminum version, it provides a superior sealing surface and improved airflow, though it requires careful filter maintenance to ensure the engine remains protected from debris.

FAQs
Is the backfire screen permanent?
The kit includes specialized backfire-resistant foam layers for 4-stroke models, which replace the traditional metal screens while maintaining safety.
Can I use any air filter with this kit?
The Powerflow Kit is designed to work specifically with Twin Air filter elements to ensure the proper seal and fitment.
How often should I re-oil the filter?
Re-oil the filter according to your riding conditions, generally every 1-3 rides or immediately after riding in heavy dust or mud.
Does this kit increase engine noise?
Because it improves airflow efficiency, you may notice a slightly deeper intake sound, which is normal.
Is this kit street legal?
The kit is intended for off-road use; check your local regulations regarding engine intake modifications.
Troubleshooting
Difficulty seating the air filter on the cage
Ensure the filter is properly aligned with the cage frame and that no debris is trapped between the foam and the aluminum mounting surface.
Airbox whistling or irregular idle
Check that the cage is fully locked into the airbox mounting tabs and that the seal is not pinched.
