Sprint Filter P14 Air Filter for Dusty Conditions – KTM 390 Adventure (2024–2026) PM293P14

The 390 Adventure this one replaced had a further step available to anyone riding in dust: its airbox was catalogued with Sprint Filter's 7-micron nonwoven as well. The 2024-on housing is not. For the current machine the fine end of the range stops here, at 14 microns and 1,800 litres per square metre per second, and that quietly changes the question being asked. It is no longer which rung of a ladder suits the riding. It is whether the last rung that exists is the right place to stand.

Key Features

• Dry nonwoven medium specified at 14 microns, flowing 1,800 litres per square metre per second
• The finest element catalogued for the 2024-on airbox — no 7-micron option is listed against it
• Finer holds back more and passes less air: the two move together, and neither outranks the other
• Dry from first fitting to last, so there is no oil to apply and none to be drawn forward
• Sits where the paper panel sat, in the standard box, nothing altered and no remap
• Cleaned with compressed air and put back, and covered for two years from purchase

Two answers instead of three

Set against the standard weave's 80 microns and 5,050 litres per square metre per second, this nonwoven arrests a good deal more and lets a good deal less through, and the direction of both figures is beyond argument. What went with the older part number is the option of going further still. The choice for a 2024-on 390 Adventure is therefore between two media rather than three, and the variable that used to sit beyond this one has moved out of the catalogue and into the calendar.

Opening the box on a loaded bike

Which matters more here than on the nakeds that share the code. Reaching the filter of a touring-packed adventure bike costs more than the same job on a Duke, and the cost is counted in luggage rather than in tools. So it is worth choosing the medium against the roads the machine really rides — dry unsealed kilometres, farm traffic, a long spell without rain — rather than against the trip imagined at the showroom. Whichever way that falls, no element in a standard airbox adds output; what a dry, washable one offers is a restriction that starts low and can be put back there.

Care and cleaning

Compressed air, held to the clean face of the PM293P14 and pushed outward, clears an ordinary load in a few minutes and asks for nothing afterwards. A heavier one wants lukewarm water and a mild detergent, rinsed until the water carries nothing away. Drying is done in open air and by nothing faster, since heat of any kind damages the medium, and the element goes back only when it is dry through. The illustrated maintenance sheet is in the Downloads tab.

Fitment & Compatibility

For the KTM 390 Adventure built between 2024 and 2026, which shares its airbox with the current 390 Duke and the Husqvarna singles beside it — seven machines on this code, set out in full in the Fitment tab. The 2020 to 2023 390 Adventure wears the same name over a different housing, so order by the model year rather than by the badge on the tank.
