I ordered these filters to replace my stock ones on a 2006 Suzuki M109R. They are an exact fit, easy install, very happy with them.

Love it. I drive a 93 Suzuki Samurai and makes more horsepower.

I use K&N air and oil filters on all my personal vehicles, currently being: Suzuki GSXR 1000, Cagiva Raptor 1000, Jeep Cherokee and Nissan Stagea. To keep them running in top order I won't go past K&N!!
