Developed in co-operation with a renowned European manufacturer, Motorex Air Filter not only offer maximum protection but also create the optimum conditions for maximum engine output.

Features;

• Motorex filters are made from specially developed polyester foams.
• Their special structural shape increases the air volume around the filter, raising intake pressure while clogging significantly slower than conventional filters in off-road use.
• Each filter is made of two layers of polyester foam, each with different porosities, flame laminated and welded into a single component to act as pre-filter and fine filter.
• All pre-oiled air filters are oiled with Motorex's state-of-the-art Racing Bio Liquid Power Air Filter Oil.
• A wide, breathable foam seal insures that no unfiltered air passes the intake.
