The 2006, 2007, 2008, 2009, 2010, 2011 and 2012 Yamaha YZ250F and YZ450F have received some great reviews from dirt bike/motocross enthusiasts. With its redesigned lightweight aluminum frame, narrow body style for improved handling and high revving engine for better throttle response, the 2006 to 2012 Yamaha YZ250F and Yamaha YZ450F are great choices for high performance and handling.

K&N Engineering designed a high flow replacement air filter, YA-2506XD, for the 2006, 2007, 2008, 2009, 2010, 2011 and 2012 Yamaha YZ250F and Yamaha YZ450F. The YA-2506XD is a washable and reusable air filter that is designed to increase power and torque while providing excellent filtration. The YA-2506XD will also fit the 2007 to 2012 Suzuki RMZ450 and RMZ250 and the 2006 Suzuki RMZ450.

The YA-2506XD is designed to replace the stock foam filter that comes with your Yamaha YZ250F or YZ450F. K&N's pleated filter design greatly increases the surface area over a foam filter allowing your engine to breath easy.

K&N's replacement filter, YA-2506XD, is custom built to fit into your existing factory air box. K&N's high flow replacement motorcycle air filters do not require any cutting or fitting. Simply remove the disposable air filter and replace it with a K&N. The easy to follow instructions provided by K&N make adding performance to your 2006 to 2012 Yamaha YZ250F or Yamaha YZ450F simple.

The YA-2506XD is made up of cotton gauze layered between two epoxy-coated aluminum wire screens that act as a backfire screen. The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton's strands. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil offer remarkable protection from the dirt and dust of off-road racing.

The 2006 to 2009 Yamaha YZ250F and YZ450F also benefit with K&N's premium oil filter, KN-141, which offers high flow rates with excellent filtration.
