Sprint Filter P14 Air Filter for Dusty Conditions – KTM 250 Duke (2024–2026) PM293P14

A catalogue that closes a listing does its reader a favour, and among the KTMs in this family only the 250 Duke gets that favour. Its earlier entry runs to 2023 and stops there; PM293P14 begins in 2024. No year is claimed twice, so a single fact — when the machine was built — turns a judgement call into a lookup. That is worth saying out loud precisely because the models either side of it are not so clearly divided.

Key Features

• Fine dry nonwoven, rated 14 microns with a flow of 1,800 l/m²/sec
• Covers the 250 Duke from 2024 onward, where the previous code ended in 2023
• No oil at any point in its life, and none to reintroduce after cleaning
• Direct fit in the production airbox: nothing modified, nothing remapped
• Serviced with compressed air, so an interval costs time rather than parts
• Two years of warranty, running from the purchase date

What a closed year range is worth

Fitment tables are read by people who are not certain what they own, which is most of us at a parts counter. A range with both ends written down can be checked against a registration document in seconds and cannot be argued with. A range left open cannot, and the reader is left inferring from a model name that manufacturers reuse for decades. Nothing about the element changes either way. What changes is how much confidence you can have before the box is opened, and here it is as much as this catalogue ever offers.

Choosing the material once the code is fixed

Three media are drawn for this housing, and they differ only in what is folded inside the same frame. The standard weave sits at 80 microns and 5,050 litres per square metre per second, this nonwoven at 14 and 1,800, and a racing cloth further out again. Finer means more held back and less let through; that exchange is the whole of the difference and it does not rank the three. It certainly does not produce power. A 250 homologated for the A2 category has its ceiling fixed by the engine and its approval, not by the panel in the airbox, and what the element honestly offers is a low intake restriction that a wash restores.

Care and cleaning

Dry servicing first: an air line applied to the clean face of the PM293P14, worked outward, until nothing further comes away. Water is the second stage and not the usual one — hand-warm, with a mild detergent, rinsed through until it leaves clear. Drying happens in circulating air and takes as long as it takes; a heat gun, a radiator or a flame will ruin the medium, so none of them is an option. Refit it dry and untreated.

Fitment & Compatibility

The P14 element for the KTM 250 Duke, 2024 to 2026, replacing the original panel in the standard airbox. Seven entries across the current KTM and Husqvarna singles carry this code, and the Fitment tab lists every one with its years. A 250 Duke built up to 2023 is covered by the earlier Sprint Filter code instead.
