At DMG Motorsports, we present the Hiflofiltro HFA3901 Air Filter (SKU 551-3901) — a precision-engineered, direct-fit replacement designed to slot straight into your factory air box with zero modification required. Built by one of the most trusted names in motorcycle filtration, this filter uses Hiflofiltro's proprietary Powerflow filtering media to deliver the clean, consistent airflow that today's high-performance engines demand. Whether you're maintaining a Cagiva Raptor 1000 or a Suzuki TL1000S, this filter restores your intake system to like-new performance without the guesswork of aftermarket sizing or fitment issues.

Hiflofiltro has been supplying original equipment manufacturers since 1963, and that OEM-grade heritage carries through into every filter that leaves the factory. Choosing this filter means choosing a part built to meet or exceed the performance of the filter your bike originally shipped with, backed by decades of manufacturing expertise and rigorous quality control.
