The materials used are the best currently available in the market. The filters are made from a single rubber frame to prevent any breakage. The filtering element is made of a special cotton fabric (4 layers) soaked in a low tack oil. It is comprised of an aluminum net treated with an epoxide solution to resist the gasoline vapors and oxidation. In addition, the cotton has the advantage of being washed out and reusable. These features guarantee a higher air flow rate from the original paper filters, minimal pressure drop of the incoming air, and therefore better engine performance. Durability: washable and reusable, no replacement needed – Wider filter surface – Maximum air permeability (4 layers of cotton) – Higher absorption and filtering – Better pressure drop ratio – Tested by international test methods Model Compatibility : Suzuki GSX-R 1000 K9 2009 Suzuki GSX-R 1000 UF K9 2009 Suzuki GSX-R 1000 Z 25th Anniversary 2010 Suzuki GSX-R 1000 ZUF 25th Anniversary 2010 Suzuki GSX-R 1000 L0 2010 Suzuki GSX-R 1000 UF L0 2010 Suzuki GSX-R 1000 L1 2011 Suzuki GSX-R 1000 UF L1 2011 Suzuki GSX-R 1000 UF L2 2012 Suzuki GSX-R 1000 L2 2012 Suzuki GSX-R 1000 UF L3 2013 Suzuki GSX-R 1000 ZUF L3 2013 Suzuki GSX-R 1000 Z L3 2013 Suzuki GSX-R 1000 L3 2013 Suzuki GSX-R 1000 UF L4 2014 Suzuki GSX-R 1000 Z L4 2014 Suzuki GSX-R 1000 ZUF L4 2014 Suzuki GSX-R 1000 L4 2014 Suzuki GSX-R 1000 L5 2015 Suzuki GSX-R 1000 A L5 2015 Suzuki GSX-R 1000 A UF L5 2015 Suzuki GSX-R 1000 UF L5 2015 Suzuki GSX-R 1000 A L6 2016 Suzuki GSX-R 1000 A UF L6 2016 Suzuki GSX-R 1000 L6 2016 Suzuki GSX-R 1000 A 30th Anniversary ABS 2016 Suzuki GSX-R 1000 UF L6 2016.
