K&N Replacement Air Filter for Suzuki GSX-R 1000 (2017-2023) – SU-1017

The K&N SU-1017 is a direct drop-in replacement air filter engineered specifically for the Suzuki GSX-R 1000 from 2017 to 2023. It slots straight into the original airbox without any modifications, freeing the GSX-R's litre-class engine to breathe more efficiently and deliver the acceleration and horsepower the platform was always capable of — all while staying fully compliant with noise and emissions regulations.

Key Features

• Optimised airflow through a multi-layered cotton gauze media that improves horsepower and acceleration without sacrificing filtration quality.
• Washable and reusable design means a single filter can outlast the engine itself, eliminating repeat purchase costs associated with disposable paper elements.
• Service intervals of up to 80,000 km between cleans, depending on riding conditions — dramatically longer than a standard OEM paper filter.
• Fully compatible with the GSX-R 1000's factory electronics, sensors and airbox; no mapping changes or hardware modifications required.
• Proven engine protection — the K&N cotton gauze construction captures harmful contaminants while allowing maximum airflow to pass through to the throttle bodies.
• Reduced environmental impact through reusability, cutting down the waste generated by disposable filter elements over the life of the motorcycle.

Heritage, Design and Filtration Technology

K&N has been refining high-flow filtration since 1969, and the SU-1017 is the product of that accumulated knowledge applied directly to one of Suzuki's most celebrated superbikes. The filter's distinctive oiled cotton gauze construction is a K&N signature — layers of precision-woven cotton pleated around a pliable wire mesh frame that holds its shape under the high-velocity airflow conditions generated inside the GSX-R 1000's airbox at full throttle. This is not a generic aftermarket element; the SU-1017 is a model-specific design that mirrors the exact geometry of the OEM filter it replaces, ensuring a perfect seal against the airbox housing every time.

Where a standard paper element progressively restricts airflow as it loads with contaminants, K&N's lightly oiled gauze maintains consistent flow characteristics between service intervals. The result is a filter that does more with the space available inside the airbox — a key advantage on a machine where every marginal gain in volumetric efficiency translates directly into sharper throttle response and stronger mid-range pull.

Installation and Maintenance

Fitting the SU-1017 is straightforward: remove the OEM element, drop in the K&N replacement and close the airbox. No jetting, no ECU reflash, no additional hardware. When the time comes to service the filter — at the manufacturer's recommended interval of up to 80,000 km — K&N's own recharger kit is used to wash, dry and re-oil the element, returning it to as-new performance. The process takes less than an hour and restores full filtration efficiency before the next outing.
