Motorex Air Filters

Motorex Foam Filter Oil, Cleaner and Care Products for Every Air Filter

Motorex has been making lubricants and cleaning products in Switzerland since 1917, and this range covers everything you need to keep a foam air filter properly maintained — filter oil, cleaner and the two-part systems that make servicing one a five-minute job rather than a mess on the workbench.

A foam filter only works if it's oiled correctly — too dry and it won't trap fine dust, too wet and it can choke airflow and hurt performance. Motorex's cleaner strips out the old oil and grime first, then the filter oil goes on evenly and tackifies to grab dust without dripping into the airbox. It's worth doing this every service interval on a dirt bike or ATV that sees dusty conditions regularly, since a clogged or under-oiled filter is one of the more common (and avoidable) causes of premature engine wear.

Pair these with a spare from our foam air filters range so you always have a clean one ready to swap in, and check out air filter oil and cleaner for other brands if you want to compare. For the wider Motorex lineup beyond filter care, browse the Motorex brand collection.
