I purchased and installed the KN Race Specific air filter on my 2011 GSXR 1000 race bike.  The race specific filter is less restrictive than a normal filter and the design allows for higher air flow, especially at lower RPM.  The filter provided a noticeable increase in low to mid RPM performance on the 2011 GSXR 1000.  I noticed the bike had more pull off the bottom, exiting corners – which is crucial for racing.  My bikes are equipped with air fuel tuners, which have a “self mapping” component.  The tuner added a marginal increase in fuel in the 3000 – 5000 rpm range, likely the result of the additional air flow.  Higher RPM performance is unchanged – as the air ducts pressurize the airbox, so air intake isn’t a problem.  This filter will increase your performance and reduce your laptimes by smoother acceleration and more power at lower RPMs, crucial for corner exit.

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.
