K&N 20-23 Yamaha YZF R1/M 998 Replacement Air Filter - YA-1020

The K&N YA-1020 Replacement Air Filter is a high-flow, direct-fit motorcycle air filter engineered specifically for the 2020–2023 Yamaha YZF R1 and YZF R1M 998cc. Designed as a drop-in upgrade over the factory paper element, this K&N filter is custom-engineered to fit your specific airbox with no modification required. If you're looking for a Yamaha YZF R1 performance air filter that installs like stock but breathes better, the YA-1020 is the go-to choice for street and track riders alike.

Key Features & Benefits

• High-Flow Filtration: K&N's pleated filter media is designed to provide increased airflow compared to a standard OEM paper element, which is intended to support increased horsepower and torque output from the 998cc inline-four engine.
• Direct-Fit / Drop-In Design: Custom engineered to fit the 2020–2023 YZF R1 and R1M airbox exactly — no cutting, trimming, or adapter required. Swaps out just like the original filter.
• Reusable & Washable: K&N replacement filters are designed for long service life. Rather than discarding a clogged paper filter, you can clean and re-oil the YA-1020 and reinstall it — a practical benefit for riders who want to minimize ongoing maintenance costs.
• OEM-Style Confidence with Performance Gains: The filter fits within the factory airbox, so it works with your stock intake system, fueling, and emissions setup without requiring additional tuning in most typical applications.
• Engineered for Yamaha's Supersport Platform: K&N designs each replacement filter to match the precise dimensions and sealing requirements of the target vehicle's airbox, ensuring no unfiltered air bypasses the media.
