Sprint Filter P08 Air Filter for Road & Track – Benelli Leoncino 800 (2024–2026) PM281S

Three motorcycles take this element, and they are not three versions of one idea: a Benelli roadster and two QJ Motor adventure-tourers, ridden on different roads by people with different reasons for buying them. The parts catalogue is indifferent to all of that, because an air filter is specified by the box it closes — sealing face, depth, frame — and those three machines share one. Which leads somewhere useful on a Leoncino page. The model itself tells you nothing about which of the media offered for this housing belongs in your bike. That answer comes from the roads you ride, not from the badge on the tank.

Key Features

• Dry woven polyester rated at 80 microns and 5,050 l/m²/sec
• Polyester threads from 22 micrometres in diameter, woven into an even mesh
• 93.13 % of 100-micron particles retained in the manufacturer’s comparison test
• Direct replacement in the standard Leoncino airbox; no modification, no remap
• Roughly twice the filtering fabric of a conventional performance element
• Washed and refitted rather than reordered; two-year warranty from purchase

The roadster’s case for the standard weave

P08 is the medium Sprint Filter designates for road and track, which is a fair description of what a Leoncino 800 does: mixed traffic, open roads, some rain, occasional enthusiasm. Its 80-micron rating and 5,050 l/m²/sec of flow are the balanced pair in the range, and balance is the right thing to want when the conditions are ordinary. It will not add power, because no slot-in element makes a standard Leoncino 800 noticeably stronger. It holds the intake restriction at a level you can restore at will, instead of one that only ever grows.

Three answers for one housing

Alongside this panel the catalogue lists a 7-micron nonwoven rated at 560 l/m²/sec for dust and unsurfaced roads, and an 85-micron racing weave rated at 15,000 for track work. The spread is deliberate, and it is a trade rather than a ranking: a finer cloth holds back more and passes less, a coarser one does the opposite, and the same shape carries all three. Choose by the air the bike actually breathes and the standard weave wins most Leoncino arguments outright.

Care and cleaning

Compressed air does nearly all of it: hold the line to the clean face and drive the load back out the way it came in. A stubborn oily film, the kind winter roads leave behind, comes off with hand-warm water and a small amount of mild detergent, then a rinse until the water is clear. Dry it in moving air only, well away from radiators, heat guns and flame, since heat rather than dirt is what ends a polyester panel’s life. The PM281S is refitted dry and untreated; its maintenance sheet is in the Downloads tab on this page.

Fitment & Compatibility

Made for the airbox of the Benelli Leoncino 800, model years 2024 to 2026, one element per machine. Three motorcycles carry this code across Benelli and QJ Motor; the complete list is in the Fitment tab.
