Dirt Bike Air Cleaners & Air Filters

Keeping engine air clean is important for any motorcycle – but maybe none more so than a dirt bike. Going off-road leads to an abundance of dirt, dust, mud and grime beating on your engine, and you’ll need a strong air filtration system to fend it off. At Dennis Kirk, we carry dirt bike air cleaners and air filters that are up to the task. These performance air system parts prevent gunk from sapping power and reducing the life of engines while allowing the airflow needed for great acceleration and throttle response.

Our dirt bike air filters are used by championship motocross riders and factory race teams in series across the globe, and will give local enthusiasts the same air-cleaning power. Modern foam air filter elements from UNI, Moose, Pro Filter and other manufacturers use a dual-stage design, with a combination of coarse and fine foam to trap particles of all sizes. Yet this excellent filtration power also allows free-flowing air to pass through the intake for improved horsepower and the jump you’re looking for when you grab the throttle.

A number of MX air filter options ensure you’ll be ready for any riding conditions. Dennis Kirk has pre-oiled air filters in stock for use in wet and muddy elements, and adding a pre-filter wrap further obstructs water. Adding a crankcase breather filter will keep your crankcase vent clean for the demands of competition, while riders with carbureted engines can get pod air filters that clamp on directly to further increase airflow and power. We also have air filter seals, replacement cages, filter skins and even replacement filter foam to extend the life of your performance filter.
