Kawasaki Polaris Sea-Doo Yamaha K&N 3.5 Race Filter/Black Top 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.
