Sprint Air Filter PM145S for KTM Duke and RC 390 motorcycles is a reusable high-performance replacement filter designed to improve intake airflow while maintaining reliable engine protection. It uses Sprint Filter’s advanced P08 polyester filtering media, which provides high permeability with more uniform filtration than many traditional paper or layered cotton filters.
The precision polyester weave uses approximately 70-micron fibres and is designed to filter debris down to around 80 microns. Reduced intake restriction can help the engine breathe more efficiently, supporting responsive throttle operation, smooth acceleration and consistent performance during street riding and track-day use.
Unlike reusable cotton air filters, the Sprint Filter PM145S does not require filter oil or specialised washing chemicals. It can be cleaned using low-pressure compressed air and reused, helping simplify maintenance while reducing recurring replacement costs. The direct-fit design installs inside compatible original KTM airboxes without permanent modification.
