Motorex Yamaha YFM400 Big Bear IRS 2007-2012 Foam Air Filter Dual Stage

Specially developed in co-operation with Twin Air, Motorex air filters not only offer maximum protection, but also create the optimum condition for maximum engine output.

Features:

• Motorex filters are made from specially developed polyester foams.
• A 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 constructed of dual layers of polyester foam, each with different porosities, flame laminated and welded into a single component to act as pre-filter and fine filter.
• A wide, breathable foam seal insures that no unfiltered air passes the intake.
