Sprint Filter T12 Air Filter for Off-Road & Extreme – Benelli Leoncino 800 (2024–2026) PM281T12

Put a row of filters in front of most people and they reach for the finest one. It reads as the careful choice: smaller openings, less gets through, nothing to regret later. The flow column is where that instinct is invoiced. This mat filters at 7 microns and is rated at 560 l/m²/sec; the standard weave for the same Leoncino airbox filters at 80 and is rated at 5,050. That is roughly a ninefold difference in the air a square metre of material will pass, the largest single step the range contains, and none of it is concealed — the figure sits in the same table as the micron rating. It is simply the half of the specification that rarely gets read.

Key Features

• Dry polyester special nonwoven with a 7-micron filtration rating
• 560 l/m²/sec of rated flow: the most restrictive medium in the range, by design
• Intended for dust, sand and unmade roads rather than for a commute
• Interchangeable with the series panel; airbox unmodified, calibration untouched
• About double the filtering area of a conventional performance element
• Serviced with compressed air again and again; two years of warranty

A seesaw, not a ladder

Finer weave, more retention, less flow. Coarser weave, less retention, more flow. Every medium in the catalogue sits somewhere on that one lever, and moving along it is an exchange rather than a promotion: a T12 is not an improved P08, it is a different tool for different air. Anyone reading the range as a quality ladder ends up buying the wrong end of it, usually the fine end, for roads that never asked for it.

When a Leoncino still wants seven microns

When the riding takes in unsealed access roads, forest tracks, dry farm country in high summer, or long stretches behind vehicles that lift whatever the surface has to offer. Roadsters go there more often than their brochures suggest, and in that air a 7-micron mat holds back what the standard cloth passes. Two things it does not do. It does not lengthen the service interval, since a fine medium loads sooner rather than later. And it does not make a standard Leoncino 800 noticeably stronger — nothing that drops into a series airbox does.

Care and cleaning

Compressed air on the clean face, moved steadily rather than blasted, is the standard service; a nonwoven holds its load close to the surface and gives it up if you are unhurried. Hand-warm water with a little mild detergent deals with anything greasy, followed by a long rinse. Drying is ambient and nothing else, because heat is the one thing this material cannot survive, so keep guns, radiators and flame away from it. The PM281T12 returns to the airbox dry, unoiled and untreated, and its maintenance sheet is in the Downloads tab on this page.
