Polaris Sea-Doo Yamaha K&N 2-1/2" Race Filter Pre Filter - K&N Performance

The K&N Flame Arrestor makes the world’s leading air-filtration technology available for marine engine use. For the first time, boat owners can experience the increased horsepower and engine protection provided by K&N's unique oiled cotton gauze and epoxied screen filter element. For high performance on the water, no other product can match the "horsepower-per buck" benefits of the K&N Flame Arrestor.

K&N flame arrestors replace the restrictive factory airbox. In most cases an adapter is required to mount the flame arrestor onto the carburetor. Some watercraft may require a slight adjustment to the carburetor's fuel circuits to allow for optimum performance.
