K&N High-Flow Air Filter | Yamaha MT-09, Tracer 9 & XSR900 (YA-9021)
The YA-9021 is the precision-engineered performance upgrade for Yamaha’s latest-generation 890cc CP3 engine. Specifically designed for the 2021+ Euro 5 models, this filter replaces the restrictive factory paper element to help the high-torque triple breathe more efficiently, ensuring smoother power delivery from a standstill all the way to redline.
Key Features
-
Optimized for the 890cc Triple: Designed to provide up to 50% more airflow than standard paper filters, supporting the increased air demands of the 2021+ engine revisions.
-
Superior Filtration & Protection: Features K&N’s signature multi-layered oiled cotton gauze media, designed to achieve up to 99% filtration efficiency while maintaining high air velocity.
-
Washable & Reusable: A "Lifetime" performance upgrade. Simply wash, re-oil, and reinstall the filter. It typically only needs cleaning every 80,000 km (50,000 miles) under normal highway conditions.
-
Direct Drop-In Fit: Precision-molded for a perfect, airtight seal in the redesigned factory airbox. It replaces OEM part numbers B7N-14451-00 and B7N-14451-01.
-
No Tuning Required: Works seamlessly with the stock ECU; however, it provides the perfect foundation for those running aftermarket "open" exhausts.

Why Upgrade Your Gen-3 MT-09?
The 2021+ MT-09 (and its siblings) features a revised intake tract designed to enhance the sound and torque of the 890cc engine. The YA-9021 "uncorks" this system further, providing a sharper throttle snap and a more visceral intake howl—that famous CP3 "scream"—especially under heavy load. It is an essential modification for riders who want to maximize the efficiency and character of Yamaha's most popular engine platform.
