K&N Flame Arrestors for Personal Watercraft

Experience increased horsepower and engine protection with K&N Personal Watercraft flame arrestors for both normal and race applications. K&N "RACING ONLY" flame arrestors have an epoxied screen filter that does not have the cotton media. Regular K&N flame arrestors come with K&N's oiled cotton media sandwiched between screen material.

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. Check with a qualified mechanic for the proper procedures.
