Uni Filter NU-2373ST Two-Stage Foam Air Filter for Kawasaki Bayou 400 & Prairie 400

**Give your classic utility quad the ultimate defense against engine-wrecking trail dust.** The Uni Filter Two-Stage Foam Air Filter (NU-2373ST) is engineered to maximize clean airflow while providing unmatched dirt-stopping performance. Designed as a direct mechanical drop-in replacement, it installs perfectly into your factory airbox exactly like the original OEM filter. Key Features: * **Advanced Two-Stage Filtration:** Built with a dual-layer, open-cell polyurethane foam design. The coarse outer pre-filter knocks down mud and large dirt particles, while the fine-pore inner layer stops microscopic grit from reaching the cylinder. * **Serviceable & Reusable:** The dual layers can be easily separated for thorough maintenance. Simply clean with a grease-cutting detergent, re-oil, and reuse indefinitely. * **Ultra-Seal Base:** Features a thin, heavy-duty seal base with a built-in grease groove, creating an airtight, leak-proof bond against your factory intake surface. * **Proudly Made in the USA** Vehicle Fitment: **Kawasaki ATV** * **KLF400B Bayou 400 4x4** — 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002 * **KVF400 Prairie 400 (2x4 & 4x4)** — 1997, 1998, 1999, 2000, 2001, 2002 📦 Shipping Policy: * **** * We ship exclusively to the **lower 48 continental United States**. * *Note: .*
