K&N air filter KA-7508 for 2008, 2009, 2010, 2011 and 2012 Kawasaki KRF750 Teryx 750
K&N has designed a replacement air filter (KA-7508) for the 2008, 2009, 2010, 2011 and 2012 Kawasaki KRF750 Teryx 750. See the complete list of applications below.

K&N Drycharger KA-7508DK sold separately for K&N air filter KA-7508

The K&N air filter is custom designed to fit into your existing factory air box. The design of the K&N air filter means adding performance is simple. Open the air box and remove the factory air filter holder. Installation is simply with K&N's detailed instructions which come complete with pictures.

Unlike disposable filters, K&N motorcycle air filters use cotton media treated with K&N filter oil that captures airborne dirt particles while allowing a high volume of air flow. More air means more power and torque when it is needed.  Particles cling to the outside of the filter and actually become part of the filtering media. The KA-7508 is also washable and reusable.

K&N also offers a Drycharger air filter wrap for those who use their Kawasaki Teryx in wet or muddy conditions. Sold separately, the K&N Drycharger is a silicone treated, polyester wrap that is made to cover the K&N air filter. The Drycharger material contains uniform micron size openings that allows adequate air flow, yet due to its silicone treated polyester repels water from the air filter. The KA-7508DK also increases the service life of the K&N air filter by keeping larger particles of dirt, sand or mud from the filter media.

K&N air filters sold for racing and off-road use are warranted against defective materials or workmanship for one year from date of purchase with no mileage limitation. That includes K&N air filters sold for ATV and motorcycle off-highway and/or dual purpose use.

The KA-7508 offers your Kawasaki Teryx the air it needs to provide the 750 cc powerplant optimum horsepower.  It is designed to increase throttle response and top end power.

VIDEO - SEMA Booth 2008

K&N showed some flare at the 2008 SEMA (Specialty Equipment Market Association) Show in Las Vegas, Nevada. Andrew Comrie-Picard’s Mitsubishi Lancer Evolution IX rally car was hanging from the ceiling at the K&N booth.

The long history of K&N, brand legacy, and technical product testing was part of the messages delivered to help people learn about our products and understand the air filtration technology behind them. K&N showcased its air filter, air intake, and oil filter products to automotive enthusiasts through story boards located throughout the booth.

This year's booth also displayed a custom Pontiac G8 and 2009 Dodge Challenger, limited edition K&N 1970 Plymouth Barracuda collector cars from Hot Wheels, visits by AMA Supercross Champion Jeremy McGrath, World Champion Drifter Vaughn Gittin Jr., NHRA Sportsman Class Driver Mike Ferderer, Second Winningest Formula D Drifter Chris Forsberg, and a whole lot more.
