🟢 PRODUCT DESCRIPTION :

Upgrade your Yamaha YZF-R1 with the K&N YA-1004 High-Flow Lifetime Engine Air Filter, engineered to deliver increased horsepower, improved throttle response, and enhanced airflow for Yamaha’s high-performance supersport platform.

Designed as a direct OEM replacement, the YA-1004 uses K&N’s advanced multi-layer cotton gauze filtration technology to significantly increase airflow while maintaining excellent engine protection.
