The name survived the 2017 redesign; the airbox did not. That makes this the one model in the range where ordering by badge rather than by year is a genuine risk, and it is the reason this element has a page of its own. The first-generation bike, built from 2013 to 2016, takes the Sprint Filter PM145S: a dry polyester element for the original box, sold as a replacement for the paper panel rather than as a modification to the intake.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpecific to the 2013–2016 airbox; the later 390 Duke takes a different element entirely\u003c\/li\u003e\n\u003cli\u003eOne layer of woven polyester, run dry at 80 µm and 5,050 l\/m²\/sec\u003c\/li\u003e\n\u003cli\u003eAround twice the filtering surface of a typical performance element\u003c\/li\u003e\n\u003cli\u003eNo oil at any point in its life, so nothing can migrate into the intake tract\u003c\/li\u003e\n\u003cli\u003e93.13 % retention of 100-micron particles against 76.42 % for four-layer oiled cotton\u003c\/li\u003e\n\u003cli\u003eCleaned and reused indefinitely, with two years of warranty from the purchase date\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eOrder by year, not by badge\u003c\/h2\u003e\u003cp\u003eModel names outlive the hardware they were attached to, and air filters are unusually unforgiving about it. An element a few millimetres out does not fit badly, it fails to seal, and an airbox that does not seal is worse than a dirty filter. Nine machines share this part — the 125, 200, 250 and 390 Duke of this generation, along with the RC models built beside them — and every one of them is defined by a span of years as much as by a name. The Fitment tab lists all nine with theirs.\u003c\/p\u003e\u003ch2\u003eWhat it changes once it is in\u003c\/h2\u003e\u003cp\u003eLess than the marketing around performance filters implies, and more than nothing. It will not make a standard 390 Duke noticeably quicker; a drop-in element inside an unmodified airbox has never done that on any road bike. What it does is start lower and stay lower. A paper panel is a declining asset from the moment it is fitted, and its decline is invisible. Polyester that gets washed returns to a known condition each time, so the way the engine breathes stops being a function of how long ago the last service was.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eAir from the clean face outward, so the dirt leaves by the route it came in. If that is not enough, warm water with a mild detergent and gentle agitation will finish the job; rinse until the water runs clean and let it dry in air, however long that takes. No flame, no heater, no hot-air gun, and nothing applied to the weave afterwards. The Downloads tab carries the maintenance sheet for the PM145S.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe P08 for the KTM 390 Duke, 2013 to 2016.
