Sprint Filter P08 F1-85 Air Filter for Racing – KTM 390 Adventure (2024–2026) PM293S F1-85

Two different motorcycles are sold as the KTM 390 Adventure, and Sprint Filter catalogues a racing weave for both. The one built up to 2023 takes one code; the one built from 2024, on the airbox it now shares with the current 390 Duke, takes PM293S F1-85. Nothing on the tank separates them, the medium designation reads the same either way, and this is the dearest of the three elements offered for the newer housing — which makes it the one where ordering by name instead of by year is the costliest mistake to make.

Key Features

• Sprint Filter's racing weave: dry polyester at 85 microns, flowing 15,000 litres per square metre per second
• More open than the 80-micron standard cloth, yet measured at 95.22 per cent against its 93.13 in the same 100-micron test
• Filtering area roughly double that of other performance filters
• Dry throughout, so no oil film can be carried onto the sensors of a modern single
• Goes into the unmodified 2024-on airbox in place of the paper panel, with no remapping
• A little over twice the price of the standard element for this housing, under the same two-year warranty

One name over two part numbers

Model names outlast the platforms underneath them, and this one did. A buyer working from the name alone has no way to land on the right element, because the name is the single thing the two generations genuinely have in common. The identifiers that hold are the build year and the panel already in the bike: lift the seat, read what comes out, and match the years quoted against the registration document. That check takes a few minutes and is worth more here than on either of the cheaper media.

What 15,000 litres per square metre per second is

A rate, measured across clean cloth, for one square metre and one second. The state that calls on it is brief and belongs to an engine held at its ceiling, which is not how a loaded adventure single spends its day. The 85-micron aperture is the price of that rate: more air through, and more of what the air is carrying through with it. That is a trade and not a promotion, and it points away from unsealed roads rather than towards them — for dust the 14-micron nonwoven is the matched answer, and for most touring the standard weave is. No element in a series airbox adds output in any case.

Care and cleaning

Compressed air at the clean face of the PM293S F1-85, directed outward, returns the weave close to where it started, and there is nothing to apply afterwards. When air alone has stopped being enough, lukewarm water and a mild detergent will do it, rinsed until the water runs clear. The element then dries in open air and only in open air — never with heat, never near a flame — and is refitted dry. Sprint Filter's maintenance sheet is in the Downloads tab.

Fitment & Compatibility

For the KTM 390 Adventure built from 2024 to 2026. Seven machines share the code, the Dukes and Husqvarna singles of the same generation among them, and the Fitment tab carries the list. Machines built to 2023 are covered by an earlier Sprint Filter code, so confirm the year first.
