K&N Replacement Air Filter

The K&N SU-1409 is a replacement air filter engineered to deliver unrestricted airflow and enhanced engine performance. Developed from K&N's motocross racing heritage, this filter utilizes a high-flow cotton gauze medium layered between aluminum wire mesh. This construction is pleated and oiled to maximize filtration capabilities and boost overall power. Its construction allows dramatically more air into the engine, which can lead to increased horsepower and improved acceleration. By maintaining critical filtration levels, it also protects your engine from dirt and dust, ensuring longevity. This K&N air filter is a direct replacement for specific Suzuki models, including the Boulevard M90 (2009-2019) and C90T Boulevard (2013-2019).
