K&N invented the pleated cotton filter more than 35 years ago for the power sports market. Designed to increase airflow, K&N filters offer more surface area (than foam filters), increased filtration and optimum air flow.

Installation of the K&N XStream Filter is easy. With the top removed, you can easily press the sides together to slide it in between your frame rails and install it into the air-box without the oily mess associated with many other air filters.

"This filter comes with a gasket, which makes it unnecessary to run grease at the base of the filter," said K&N Powersports Brand Manager, John Jump. "It's a nice benefit and makes for a very clean filtration system. On this particular filter, you mount the gasket directly to the airbox."

Kyle Krause, who currently races Expert in the Best in the Desert and WORCS Series, has been racing for 19 years now. "I ran the new MX XStream on a 450," said Kyle. "I noticed more power right away and the filter is very easy to install and clean.

Cleaning is a simple process and K&N offers a filter care service kit (sold separately) with everything needed to clean and re-oil your filter numerous times. K&N's larger filtration area offers riders longer service intervals meaning more riding and less cleaning.
