Yamaha Grizzly 660 & Raptor 350 UNI Two-Stage Foam Air Filter | NU-3244ST

For over forty years, UNI Foam Air Filters have been unsurpassed in both engine protection and overall performance. Built for riders who demand reliable filtration without sacrificing airflow, UNI's unique two-stage design produces excellent horsepower and torque while protecting your engine's cylinder from destructive grit.

The two-layer design features a coarse, large-pore outer pre-filter to trap larger dirt particles and debris, while the fine-pore inner layer keeps air moving freely while catching any remaining fine dust. This dual-stage setup allows your machine to run longer before requiring service, making it ideal for both recreational trail riding and hard farm or industrial use.

Features:

• Dual-Stage Foam Construction: Maximum dirt-holding capacity and advanced engine protection.
• Uni-Seal Base: Features a unique grease groove on the sealing surface for an airtight, snug fit against the factory airbox.
• OEM-Style Fitment: Designed to drop directly into your stock airbox exactly like the original factory filter.
• Washable & Reusable: Easy to clean, re-oil, and reuse—built to last the life of your machine.
• Made in the USA
