Customer Feedback

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.

The day after ordering the replacement air filter I looked down our long driveway seeing a small box. When I brought the box into the house opened it I saw a smaller box inside with K & N picture on the smaller box. Wow That delivery was almost too quick The installation was also very quick. What took the most time was walking to my tool box and grabbing a screw driver to fasten the filter. After 5 minutes of installing the new K & N replacement air filter. I started up the Suzuki Dual Sport 650 took it for a spin noticing the bike had more power and was running better. Thank You K & N. No other company on Earth can design & manufactures air filters that compare with your products.
