K&N High Flow Air Filter for Yamaha YZF R1 (2020-2025) - YA-1020

K&N High-Flow Air Filter | Yamaha YZF-R1 & R1M (YA-1020)

The YA-1020 is the precision-engineered performance upgrade for the latest generation of Yamaha's flagship superbike. While the R1 received a major engine and electronics overhaul in 2020 to meet Euro 5 standards, the YA-1020 ensures the 998cc Crossplane (CP4) engine remains unhindered, providing the high-velocity airflow required for 200hp+ performance.

Key Features

• Euro 5 Optimization: Designed specifically to improve the breathing of the 2020+ R1, which features a revised intake system and cylinder head. It provides up to 50% more airflow than the stock paper element.

• CP4 Harmonic Protection: Features K&N’s signature multi-layered oiled cotton gauze media. This media is uniquely suited to handle the aggressive intake pulses of the Crossplane crankshaft, maintaining steady air pressure for the fuel injectors.

• Washable & Reusable: A "Lifetime" filter. Instead of discarding expensive OEM filters at every service, you can wash, re-oil, and reinstall the YA-1020. It is designed to last the entire life of your motorcycle.

• Direct Drop-In Fit: Precision-molded for a perfect, airtight seal in the updated 2020+ airbox. It replaces Yamaha OEM part number B3L-14451-01-00.

• Fueling Compatibility: Engineered to work perfectly with the stock ECU and Yamaha’s complex IMU-driven electronics, though it is the ideal foundation for riders adding a 3/4 or full titanium exhaust system.

Why Choose K&N for your 2020+ R1?

The 2020–2025 R1 is a masterpiece of refinement, but the factory air filter is designed primarily for noise suppression and extreme service intervals. The YA-1020 "uncorks" the intake, resulting in a sharper throttle snap and a more visceral intake roar as the YCC-I variable stacks actuate. For owners of the R1M, this filter is a standard "day one" upgrade to ensure the bike's mechanical performance matches its elite electronic suspension and carbon fiber pedigree.
