More Power and Acceleration. This K&N Drop-In Air Filter replaces your Mustang's stock paper filter with a durable air filter that traps contaminants to improve the intake of your ride. This leads to more horsepower and improved acceleration to bring your Mustang to peak performance on the road or at the track.

Pre-Oiled Cotton Gauze Construction. Upgrade your Mustang's stock filter with this K&N Drop-In Replacement Air Filter. The layered cotton gauze construction has superior filtration capabilities, and the unique oil coating makes the cotton fibers slightly tacky to stop even more contaminants from reaching your engine.

Washable and Reusable Filter. Reusing this K&N Drop-In Replacement Air Filter is easy. Just remove the filter from your air box, clean it thoroughly, reapply the filter oil, and place the filter back in your air box. Each filter lasts up to 50,000 miles between cleanings, depending on driving conditions.

Drop-In Replacement. This K&N Replacement Filter is a direct-fit drop-in upgrade for your Mustang. It fits into the factory air box and doesn't require any cutting or drilling, so it does not void your vehicle's warranty.

Million-Mile Warranty. K&N backs all of its air filters with a million-mile warranty. This means that if you aren't satisfied with your filter for any reason within a million miles of use, you can bring it back for a replacement. Some restrictions apply, so check the manufacturer's warranty before filing a claim.

Application. This K&N Drop-In Replacement Air Filter is designed to fit all 1983-1986 Ford Mustang models with a 3.8L engine.
