Air Filter Housings

About Air Filter Housings

The air filter housing, or airbox, holds the filter and seals it so that only filtered air reaches the engine. The parts in this small category are airbox covers, which close the box and protect the filter from mud, water and dust.

A cover is matched to a specific machine. The two listed here are an airbox cover for the KFX700 and a black airbox cover, so check the make, model and years carefully rather than assuming a general fit. When you fit one, check that it sits flat and that any seal is clean and in place. A cover with a crack or poor seal lets unfiltered air in, and that can wear the engine quickly.

Brands in this category include Outerwears and Maier. For the filters that go inside, see Air Filters, and for the connecting parts see Air Hoses, Lines & Pipes. The wider group is Air Intake & Fuel Delivery. Pick your machine in the Ride Finder at the top of the page.

FAQs on UTV and ATV airbox covers

What does an airbox cover do?

An airbox cover closes the housing around the air filter, so air has to pass through the filter before it reaches the engine. It also keeps water, mud and dust out.

Will an airbox cover fit my ATV?

Covers are made for specific machines, so match the make, model and years in the listing to yours. The ones in this category are listed by model, such as the KFX700. Use the Ride Finder at the top of the page to check.

Can I ride without the airbox cover?

No. Without the cover, the filter and intake are exposed to dirt and water, and unfiltered air can damage the engine. Fit the cover fully and make sure it seals each time you open the box.

How do I check that an airbox cover seals properly?

Clean the mating surface, check that any rubber seal is in place, and close every clip or screw. The cover should sit flat with no gap. Replace a cracked cover.
