The Outerwears ATV Air Box Cover Kit, manufacturer part number 20-1057-02 and vendor part number 25-5630B, is designed to replace the original airbox lid on select sport ATVs. This practical airbox cover solution increases airflow reaching the air filter while retaining filtering capability, helping support consistent engine performance during recreational riding, trail use, and off-road applications.
Built for a straightforward installation, this kit provides a cost-effective alternative to replacing or modifying the complete airbox assembly. The cover is intended to fit the factory airbox configuration on compatible vehicles and can be installed in place of the stock lid. Its design allows additional air to enter the intake system while helping reduce exposure to dirt and debris before air reaches the filter.
Fitment includes the 2004–2006 Kawasaki KFX 400 and the 2003–2006 Suzuki LT-Z400 QuadSport Z. Verify the vehicle year, model, and existing airbox configuration before ordering to ensure proper compatibility. The Outerwears 20-1057-02 airbox cover kit is a suitable replacement or performance-oriented upgrade for riders seeking improved intake airflow without eliminating air filtration.
