Sprint Filter P08 Air Filter for Road & Track – BMW F 800 GS (2007–2018) PM35S

Two motorcycles have been sold as the F 800 GS, and they share nothing in this part of the machine. BMW built the first from 2007 to 2018, shelved the name, then brought it back for 2023 on a bike with a different engine, a different airbox and a different filter. No badge separates them. Only the year of build does, and the PM35S belongs to the earlier one — the machine that left the factory up to 2018. Settling that is the whole task before anything gets ordered.

Key Features

• Dry woven polyester, one layer thick, never oiled at any point in its working life
• 80 µm apertures and 5,050 l/m²/sec of rated flow: the P08 is the road and track member of the range
• Fibres of ø 22 microns and up — a thread measurement, not the size of the openings
• Close to double the filter area of other performance panels, carried in the standard frame
• A straight exchange for the original element, with airbox and mapping left as BMW made them
• Cleaned and refitted for the motorcycle's working life, warranted for two years from the purchase date

Why a five-year gap decides more than a name

Model names get reused; housings do not. An air filter is specified by the box it seals into, so what a parts list answers is never what a motorcycle is called but what was built around it. Between 2018 and 2023 nothing wore this badge, and the machine that picked it up came from the later F platform with an intake of its own. Search by name and both parts will be offered; they are not interchangeable in either direction. The registration document ends the argument — a build year up to 2018 means this element.

What the earlier bike gets out of it

The first F 800 GS was the off-road-biased machine of its range, spoked wheels and all, and plenty have been ridden that way. So the airbox on this one is a lid that gets opened. A dry element repays that: out it comes, an air line takes the load back off, in it goes, so inspecting it costs a few minutes and there is a known condition to return to, rather than a judgement about whether the paper will do another interval. It adds no power — a panel in the series box never does — and it asks for no change to the fuelling.

Care and cleaning

The service tool is an air line: apply it to the clean side, blow outward, until the weave runs clear. After a wet or muddy day, warm water and a mild washing-up detergent finish what the air left behind, followed by a rinse that comes away clean. Drying happens in moving air at room temperature; heat ruins polyester, so ovens, blowers and open flame are out, and it goes back dry and unoiled.

Fitment & Compatibility

Made for the BMW F 800 GS built from 2007 to 2018, and for that machine only. The F 800 GS sold from 2023 onward is a different motorcycle with a different airbox, and it takes a different Sprint Filter part number — not this one. Inside its own list, PM35S covers ten machines from two makes — the F 700 GS, the F 800 R, the GT and a Husqvarna among them — all shown with their years in the Fitment tab.
