Replacement Air Filters and Filter Cartridges

Cross-reference numbers and the exact model year

Titles name machines such as ATVs, side-by-sides and compact tractors, often with a year range. Match by the manufacturer's part number or the cross-reference number printed on the old element, because the same model can use a different air box between years. Items listed as universal fit have to be measured for length, width, thickness or diameter and shape. Look at the seal edge too: a filter that is slightly small lets dust bypass into the engine.

Paper, foam or cartridge: how the element is cared for

Pleated paper elements are replaced, not washed. Foam elements are cleaned and re-oiled, and some cotton-gauze types are washed and re-oiled too. Dusty trails, farm work and sandy ground clog filters sooner than road use, so inspect often. Purifier and air conditioner filters are sold for one unit; use the listed model number, and for respirator cartridges use only the type named for your mask, as particulate and gas filters are not interchangeable.

Questions about Replacement Air Filters and Filter Cartridges

How often should I replace an ATV air filter?

Follow the interval in the owner's manual, but shorten it for dust, mud or sand. Inspect the filter before dirty rides, and replace paper elements or clean foam ones as soon as air flow looks restricted.

Can I wash a paper air filter?

No. Water damages the paper fibers, and strong compressed air can tear holes in them. Replace paper elements; only foam and certain cotton-gauze types are designed to be cleaned and re-oiled.

What happens if the filter is slightly too small?

Gaps at the edge let unfiltered air and dust into the engine, which wears cylinders and rings quickly. Match the part number and dimensions, and check the seal sits fully in its housing.
