Air Filter Oil, Filter Cleaner & Filter Care Products
The air filter is the last line of defense between your engine and the dirt, dust, sand, and debris that powersports riding kicks up in enormous quantities. A filter that is clean and properly oiled stops that contamination before it reaches the engine. A filter that is dirty, over-oiled, under-oiled, or damaged lets it through, and the abrasive particles that enter an engine past a compromised air filter cause cylinder, piston, and ring wear that accumulates with every ride until a top end rebuild becomes necessary far earlier than it should be. Air filter maintenance is one of the simplest and most impactful routine maintenance tasks available, and doing it correctly requires the right products applied in the right way at the right intervals.
Filter maintenance is more nuanced than most riders appreciate at first. An air filter that is clogged with dirt restricts airflow and causes the engine to run rich, lose power, and in severe cases draw oil past the rings from the increased intake vacuum. But an air filter that is over-oiled is almost as problematic, as excess oil migrates into the airbox and intake tract, coats the throttle body or carburetor components, and in carbureted engines can contaminate the pilot circuit and affect fuel delivery. Proper filter care means cleaning the filter thoroughly to remove all contamination, applying the correct amount of filter oil evenly across the entire filter surface, and allowing adequate time for the oil to fully penetrate the filter foam before reinstalling. Mad Lads Moto stocks air filter oils, filter cleaners, and complete filter care kits for dirt bikes, motocross machines, enduro bikes, ATVs, UTVs, and street motorcycles. Here is what we carry:
- Air Filter Oils - Foam air filter oils in spray and liquid formulations designed to coat the filter foam evenly, provide maximum dust and particle retention, and resist washing off in wet and muddy conditions while allowing adequate airflow through the filter medium.
- Air Filter Cleaners - Dedicated air filter cleaning solutions that dissolve and remove accumulated dirt, old filter oil, and contamination from foam filter elements without damaging the foam structure or the adhesive that bonds multi-layer foam filters together.
- Complete Filter Care Kits - Bundled filter maintenance kits that include both cleaner and filter oil in a single purchase, providing everything needed for a complete filter service without sourcing products separately.
- Filter Skins & Pre-Filters - Foam pre-filter skins that fit over the primary air filter to capture coarse dirt and debris before it reaches the main filter element, extending primary filter service intervals in extremely dusty conditions like desert and dune riding.
- Filter Cages & Hardware - Replacement air filter cages, filter mounting hardware, and airbox components for machines where the filter cage has cracked or the mounting hardware has been damaged or lost.
- Airbox Accessories - Airbox plugs, airbox covers, and airbox accessories for blocking the intake during washing to prevent water ingestion, and for modifying airflow characteristics in performance applications.
The frequency of air filter maintenance should be driven by riding conditions rather than a fixed interval. A filter used in extremely dusty desert conditions may need cleaning and re-oiling after every single ride. The same filter used on a groomed motocross track with minimal dust may last several rides between services. The reliable way to determine when the filter needs attention is a visual inspection before every ride: remove the filter, hold it up to a light source, and check whether light passes through the filter medium evenly. A filter through which you can see light clearly is still serviceable. A filter where the foam is uniformly dark and light no longer penetrates needs cleaning before the next ride. A filter that has developed holes, tears, or areas where the foam has compressed and lost its structure needs replacement regardless of how clean it appears.
