Twin Air - KTM Air Filter

Twin Air – KTM Air Filter

The Twin Air KTM Air Filter delivers the same championship-winning performance trusted by KTM factory riders across motocross, enduro, and rally. With Twin Air’s original dual-stage foam design, this filter provides maximum airflow while keeping even the finest dust and debris out of your engine — making it one of the most proven upgrades you can install on your bike.

The outer coarse-pore foam blocks heavy contaminants like dirt, mud, and sand before they reach the engine, while the fine-pore inner foam captures the smallest particles without restricting air. Both layers are fused together, eliminating the gap where debris can get trapped in inferior two-piece filters. The result is consistent power and long-term engine protection in every condition — from deep desert dust to wet, muddy tracks.

Built to last, Twin Air filters use a special adhesive that withstands repeated cleanings and solvents without breaking down. They’re slightly smaller than stock filters, allowing more airspace inside the airbox for better circulation and improved throttle response. A flat, greaseless sealing ring ensures a perfect fit and airtight seal, keeping every bit of unfiltered air out.

Why We Like It:
This one’s a BTO staff favorite for a reason — it’s the same filter design trusted by KTM’s world championship race teams, built for riders who demand performance and protection in every condition. The dual-foam setup handles everything from fine desert dust to sloppy mud without choking airflow, keeping your bike running crisp and strong all day. It’s easy to clean, lasts, and always fits perfectly. Whether it’s race day or a weekend trail ride, this is the filter we keep in our own KTM dirt bikes — reliable, efficient, and proven where it counts.

Why It’ll Work for You:
This filter gives your KTM the airflow it needs while protecting your motor from dust, sand, and grime that can cause costly wear. The dual-foam design keeps your engine breathing clean in all conditions, and it’s easy to clean and reuse. Whether you’re racing, trail riding, or adventuring, it’s a low-maintenance upgrade that adds serious reliability and performance.
