It blocks it by building a layer, and a layer's effect on the air depends on how thick it is rather than on how much of it there is. Spread the same day's load across twice as much material and it lies at half the depth. That is the whole mechanism behind this part number, which the catalogue credits with a hundred per cent more filtering surface than the standard-size version of the same fourteen-micron mat.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDry special non-woven polyester closing to 14 microns\u003c\/li\u003e\n\u003cli\u003eA hundred per cent more filtering surface than the standard-size element for this airbox\u003c\/li\u003e\n\u003cli\u003eRated flow of 1,800 l\/m²\/sec of material, against 5,050 for the standard weave\u003c\/li\u003e\n\u003cli\u003eNo oil when new, none after washing, nothing to be carried onto the sensors\u003c\/li\u003e\n\u003cli\u003eGoes in where the paper panel came out — no adapter, no cutting, no remapping\u003c\/li\u003e\n\u003cli\u003eBlown clear and refitted rather than thrown away, with two years of warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDepth, not weight\u003c\/h2\u003e\u003cp\u003eA loaded element is a filter with a second filter growing on its face, and the second one eventually decides matters. Early on that layer is doing useful work; later it is the reason the resistance has climbed. Since the layer builds at a rate set by how much air crosses each patch of material, halving the air per patch halves the rate at which depth accumulates. The element does not stay clean any longer — it collects exactly as much as before — but it stays open longer, which is the only part of the story an engine can tell the difference between.\u003c\/p\u003e\u003ch2\u003eWhat that is worth on a roadster\u003c\/h2\u003e\u003cp\u003eModestly more than it sounds, because a naked boxer gives its rider almost nothing to go on. There is no gauge for intake restriction and the engine management quietly accommodates whatever the filter is doing, so a fourteen-micron mat can load a long way before anything is noticeable at all. Postponing that is worth having; calling it a performance change is not. This element does not make a standard R 1200 R noticeably stronger, and neither would any other panel inside an unmodified airbox. What it offers is a longer run at the condition the motorcycle left the workshop in.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eA mat holds its load in the depth of the fibres rather than on top of them, which sets the direction of the work: the air line goes on the face turned towards the engine and blows outwards, so the dust retreats along its own path instead of being driven further in. When compressed air stops making a visible difference, hand-warm water with a trace of mild detergent finishes it, rinsed until the water runs clear. Then only moving air dries it — no heater, no oven, no flame — and the K142P14 is refitted dry.

Six machines carry this part number: the R, the RS and the RT of the 1200 generation and the same three models in the 1250 generation. Each appears with its years in the Fitment tab.\u003c\/p\u003e","brand":"Sprint Filter","offers":[{"title":"Default Title","offer_id":53533238493450,"sku":"K142P14","price":114.24,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/K142P14.png?v=1787140741","url":"https:\/\/inter-pace.com\/en-bg\/products\/sprint-filter-p14-air-filter-bmw-r-1200-r-k142","provider":"Inter-Pace","version":"1.0","type":"link"}
