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.
K&N flame arrestors replace the restrictive factory airbox. In most cases an adapter is required (for adapters see pages 30 & 31) 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.

The Outerwears Pre-filter is an excellent solution to
prevent water from entering into the engine without
restricting air flow or causing a loss in performance.
An Outerwears Pre-Filter is designed to be water repellent
and will reduce the risk of water entering through an air
intake system. Outerwears offers water repellent pre-filters
for K&N, Tau Ceti, ProK and R&D performance air filters
and flame arrestors.
