About Pro Filter

Pro Filter is a powersports-focused filtration brand operating under the Maxima family of products, long trusted by riders, racers, and wrenchers who demand proven performance from every component on their machine. Whether the terrain is a sandy desert trail, a muddy motocross track, or a tight forest single-track, Pro Filter engineers its products to handle the harshest intake and oiling conditions that powersports equipment can throw at them.

At the heart of the Pro Filter lineup are two core product families: air filters and oil filters. Each product line reflects a focused commitment to filtration science rather than a one-size-fits-all approach, giving riders application-specific solutions that are built around the demands of motorcycles, ATVs, and side-by-sides.

Air Filtration Built for the Dirt

Pro Filter's premium air filters are constructed from high-quality, chemical-resistant, open-cell polyurethane foam. The brand's signature dual-stage foam design fuses two layers with distinct pore sizes: the outer layer catches larger dirt and debris particles, while the inner denser layer traps fine sand, powder, and microscopic contaminants before they can enter the engine. This architecture helps the filter resist plugging even under sustained heavy dust loads, preserving both airflow and engine longevity.

For riders who prefer a no-fuss maintenance routine, Pro Filter's Ready-to-Use air filter line comes pre-oiled with Maxima's FFT (Foam Filter Treatment), so there's no separate oiling step required before installation. Air filter seams are welded with industrial-strength adhesive, and each filter ships with a rubber grommet that locks the element securely to the cage — eliminating tearing under vibration and preserving the filter's structural integrity throughout its service life.

Oil Filtration with M-Pleat Technology

On the oil side, Pro Filter's engine oil filters are built around proprietary M-Pleat technology — a structural paper media design that increases total filtration surface area and boosts contaminant-holding capacity, extending filter life by 20–30% compared to conventional media designs. Spin-on models include a silicone anti-drain-back valve that maintains oil pressure at startup, reducing the critical window when engine components are most vulnerable to wear. A pre-lubricated gasket ensures a reliable seal at installation, and every filter is 100% leak-tested before leaving the factory.

Pro Filter oil filters also feature a 17mm hex removal nut as a standard fitment — a practical touch that makes filter changes cleaner and more straightforward, and the nut comes pre-drilled for safety wiring on competition builds.

Engine Hardware and Accessories

Rounding out the catalog, Pro Filter offers a selection of engine hardware such as billet oil filter covers, which are engineered to increase oil flow and help manage heat in hot-running 4-stroke engines. These accessories complement the core filter lineup and reflect the brand's broader commitment to engine protection beyond just the filter element itself.

For any rider serious about protecting their engine — whether on the trail, at the track, or in the garage — Pro Filter delivers a filtration solution that is dyno-tested, race-approved, and backed by the expertise of the Maxima brand.
