UNI CVT Air Filter for Yamaha Rhino YXR660F 2004‑2007 & YXR450F 2006‑2009 – Replaces 5UG‑E4451‑00 – Must‑Have CVT Protection

OVERVIEW

This UNI two-stage CVT air filter protects the Yamaha Rhino's transmission by blocking sand, dust, and trail debris that can cause expensive gear failures. Built with durable multi-layer foam media, this fully washable and reusable element replaces the ineffective factory rain shield to deliver cleaner airflow and maintain safe operating temperatures. Engineered specifically for Yamaha Rhino models, this upgrade ensures reliable CVT performance during aggressive off-road use.

ENGINEERING & PERFORMANCE

The dual-filter foam construction provides efficient particulate capture while supporting high airflow rates necessary for effective CVT cooling and component cooling. This robust media resists rapid clogging in dusty conditions, helping to stabilize internal pressures and reduce thermal stress on transmission components over long service life. Designed as a direct upgrade over the stock intake, the filter mounts securely to the CVT snorkel tube behind the driver's seat, eliminating unfiltered air intake paths and preventing contamination leaks. The reusable design eliminates the need for frequent replacements, offering a practical solution for sustained off-road operations.

WHY RIDERS CHOOSE THIS

Riders upgrade to this filter because it addresses a common vulnerability in the Yamaha Rhino's stock design, where the original shield often fails to stop abrasive dirt from destroying the CVT. The two-stage UNI foam technology ensures that engines working in dunes, mud, and heavy dust receive protected airflow, which preserves clutch packs and bearings while improving overall drivetrain reliability. Its washable build allows owners to recycle the filter indefinitely, turning a recurring expense into a long-term asset that delivers consistent protection season after season. The precise snorkel-tube mounting provides a secure seal without modification, giving riders peace of mind that their transmission stays cool and clean regardless of terrain conditions.
