Description

The RP-5103 Universal Air Filter is constructed from an oiled cotton filter media. It comes with a K&N embossed carbon fiber top and base for strength and durability. The carbon fiber element adds to the light-weight design and gives this filter a smooth glass like finish. The RP-5103 is a clamp-on filter that has an inside flange diameter of 3 7/8 inches and a flange length of 15/16 inches. The base is 12 inches by 6 inches and the filter height is 7 inches.

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.
