Description

K&N Universal air filters are designed and manufactured for a variety of applications including racing vehicles, RC cars, generators, snowmobiles, tractors and other applications. Regardless of the angle or offset diameter of the air intake, there is probably a K & N universal air filter for your equipment. All filters are constructed with ultra-strong moulded flexible rubber flanges that absorb vibrations and allow a secure attachment and can also be stretched for up to 1/16 inches (1.5 mm) to fit in between sizes. K&N universal air filters are washable and reusable.

Key Features

ENGINEERED POWER: State-of-the-art filtration media provides up to 50% more airflow than disposable paper filters to increase power and acceleration. Clogged or dirty air filters can reduce your vehicle’s acceleration by up to 10%.

EASY INSTALLATION: Pre-oiled and built with simple clamp-on design. One of the easiest and most cost-effective upgrades for your vehicle for quick performance gains.

SAVES MONEY: K&N high-flow replacement air filters will save you $250 over 10 years by avoiding disposable filters.

ECO-FRIENDLY: Using a washable, reusable product helps reduce replacement waste. A K&N filter will last longer than 10 disposable filters.

WORLD CLASS PROTECTION: Pushing the limits of engine protection by protecting your engine from harmful contaminants.

LOW-MAINTENANCE DESIGN: 50,000 miles before your first cleaning under normal highway driving conditions.

HIGH QUALITY: Made in America.

RACE TESTED: The Official Air Filter of NASCAR. Trusted on the racetrack—made for your vehicle.
