Foam Filter TwinAir   Over 40 years ago, the sandy, gravelly soils of the Netherlands - and the resulting engine failures - proved that foam and paper filters provided airflow to riders but failed to offer protection.   The breakthrough of Twin Air, the combined dual-layer design unites performance and protection.   The fused layers of open-pore foam and fine inner foam capture even the smallest particles.   The new, rounder design increases airflow. This also applies to the minimized seams, made possible by a revolutionary micro-adhesion process: shorter seams = more foam = more flow.   - with flowable, backfire-resistant foam laminated to the inside of the filter - washable and reusable (40 to 50 times is common) - dual-layer foam (according to specifications with equally sized and distributed cells) - high quality (hand-assembled and checked for perfect fit)

Hiflo Premium Oil Filter   The Hiflo Premium Oil Filters provide optimal benefits for the customer and impress with the best quality. Only high-quality materials are used in the manufacturing of the filters.   As the only filter manufacturer, Hiflo has its filters tested and certified by TÜV Süddeutschland. The filters are compared with the respective original filter in all relevant criteria. The test can only be passed successfully if the Hiflo filter meets or exceeds the values of the original filter. This ensures that all filters meet the quality requirements of the original equipment.   Hiflo also offers the largest range of filters for motorcycles and ATVs.

Mahle Oil Filter   As one of the world's leading filter manufacturers and original equipment suppliers for BMW motorcycles, Mahle has always stood for quality and technology.   Mahle oil filters reliably keep dirt particles out of the lubrication circuit, thereby maintaining both the oil quality and the performance and efficiency of the engine.   Advantages of Mahle oil filters:   - Cold start resistance ensured by a stable pleat geometry - Reliable separation of contaminated and filtered oil through high-quality sealing materials and precisely fitting connection parts - Load peaks of up to 20 Bar are compensated by the high pressure resistance of the housing - Oil supply is always ensured by the pressure relief valve (in the case of viscous oil, as is present during cold start phases or at low outside temperatures, as well as with a heavily contaminated filter element due to exceeding the change interval) - The non-return valve prevents the filter from draining when the engine is off and ensures quick oil supply during engine start
