K&N Replacement Air Filter for Yamaha YZF-R1/M RN32, RN49 & RN65 (2015-2026) YA-1015

Built to meet and exceed OEM safety and emissions standards, the K&N YA-1015 replacement air filter slots directly into the stock airbox of the Yamaha YZF-R1/M across chassis codes RN32, RN49 and RN65 — no modifications, no compromises to the factory electronics or regulatory compliance.

Key Features

• Direct OEM replacement: fits the stock airbox on YZF-R1 and R1M (RN32, RN49, RN65) without any airbox modification or fuelling remap.
• Compatible with factory vehicle electronics: works seamlessly with the R1's stock ECU, sensors and emissions hardware — no warning lights, no compliance issues.
• High airflow with superior filtration: the layered oiled cotton gauze media delivers more air than a standard paper element while maintaining genuine engine-protection filtration levels.
• Performance gains without regulatory compromise: engineered to improve horsepower and acceleration without affecting exhaust emission or noise regulations.
• Washable and reusable for the life of the engine: clean with K&N Recharger kit and reinstall — no repeat purchase costs over the bike's lifetime.
• Extended service intervals: under normal conditions the filter requires cleaning only every 80,000 km, slashing routine maintenance effort.
• Environmentally responsible: eliminating disposable paper elements reduces landfill waste across the full ownership period.

Drop-In Performance, Factory Safety Standards Preserved

The YA-1015 is designed around the principle that performance gains should never come at the expense of safety or legality. K&N's engineering process validates each replacement filter against OEM fitment dimensions and airflow specifications, ensuring the unit seats correctly in the airbox, forms a complete seal against unfiltered air ingestion, and operates without triggering diagnostic faults on the R1's sophisticated ride-by-wire system. Riders who require a filter that passes a standard technical inspection will find the YA-1015 a straight-forward, confident choice.

Construction & Long-Term Reliability

The filtration media consists of multiple layers of cotton gauze precision-pleated to maximise surface area within the OEM footprint. The gauze is lightly oiled to trap fine particulate matter that would otherwise reach the throttle bodies and combustion chambers. The supporting frame is formed from a durable, pliable material that maintains its shape under the high-rpm pressure pulses characteristic of the R1's crossplane inline-four. Unlike a paper element that degrades with moisture or age, the K&N cotton media retains its structure and filtration efficiency through repeated wash-and-re-oil cycles over the entire service life of the engine.

Fitment & Compatibility

The K&N YA-1015 is a confirmed direct fit for the following models:

• Yamaha YZF-R1 — chassis RN32 (2015-2016), RN49 (2017-2019), RN65 (2020-2026)
• Yamaha YZF-R1M — chassis RN32 (2015-2016), RN49 (2017-2019), RN65 (2020-2026)

No airbox modification, adapter or jetting change is required. Refit uses the original retaining clips and sealing surfaces of the stock airbox.
