Description

K&N XStream Air Flow Tops replace the top of your existing round filter and add a new dimension to engine breathing by feeding your engine all the air it can use. They are washable and reusable just like other K&N Air Filters.

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.
