K&N Performance Air Filters for Harley-Davidson Motorcycles

Upgrade your Harley-Davidson with a K&N Performance Air Filter, designed to improve airflow while providing dependable filtration and long-term engine protection.

Our range of K&N air filters for Harley-Davidson motorcycles covers a wide selection of cruiser, touring and performance models. Popular applications include the Harley-Davidson Sportster, Street Bob, Fat Bob, Low Rider, Softail, Road King and Street Glide, along with many more current and previous-generation Harley-Davidson motorcycles.

K&N motorcycle air filters are designed as a direct replacement for the standard Harley-Davidson air filter, using a washable and reusable high-flow filter design that can be cleaned and serviced rather than replaced at every filter change.

Harley-Davidson Performance Air Filters

A high-flow air filter is a popular upgrade for Harley-Davidson motorcycles fitted with an aftermarket exhaust, intake upgrade, ECU tuning or other performance modifications, helping reduce intake restriction and allowing the engine to breathe more efficiently.

This makes K&N filters particularly well suited to Harley-Davidson models where intake and exhaust upgrades are commonly combined as part of a wider performance setup.

K&N filters are also an excellent option for riders simply looking for a quality reusable replacement for the original factory air filter.

At P3 Tuning, we work with tuned and modified motorcycles every day, so we understand the importance of getting the intake, exhaust and fuelling working together correctly as part of the complete setup.
