Sprint Filter PM281T12 air filter

The facts.

DescriptionThe whole story▼

There is a simple test for whether a TRK 902 Xplorer needs this element, and it takes place in the mirrors. If the view behind you on a typical ride is clear road, the standard woven panel is the right part. If it is regularly a brown cloud, your own or that of the bike ahead when you swap places, the air entering the airbox carries far more solids than any road filter is drawn for. The T12 is Sprint Filter's medium for exactly those conditions: off-road, sand and extreme dust.

Key Features

  • Dry polyester special nonwoven with 7 µm filtration
  • 560 l/m²/sec of rated flow, the most restrictive medium in the range by design
  • Meant for sand, desert tracks and long gravel stages, not for commuting
  • Fits the unmodified TRK 902 Xplorer airbox in place of the paper element, no remap
  • Roughly double the filtering surface of other performance filters
  • Never oiled, regenerated with compressed air, two years of warranty

What seven microns buys, and what it costs

A 7-micron mat holds back particles that the 80-micron weave lets through, and on a gravel stage those are the ones that matter, because they are small enough to reach the cylinders. The cost is printed alongside: 560 l/m²/sec against 5,050 for the standard P08 in the same airbox, about a ninth of the flow. Finer weave means more retention and less flow; the T12 is not a better P08, it is a tool for different air. It also fills sooner, so on a dusty trip it wants cleaning more often, not less. And it will not make a standard TRK 902 Xplorer stronger, because no drop-in element does.

When the mirror says road

Then leave it on the shelf. On tarmac the T12 restricts the engine for no benefit, and a TRK 902 Xplorer ridden mostly on roads is better served by the P08. Price is no argument either way: the T12 costs about four fifths of the standard element, so the cheaper part is not automatically the economical one. Keeping both is a reasonable plan: the T12 goes in before a trip with long unsurfaced sections and comes out afterwards, and since both are washable, neither is used up by the swap. The P08 F1-85, also listed for this airbox, is a racing weave and has no place on a dirt road.

Care and cleaning

After a dusty day, work compressed air slowly from the clean side of PM281T12 outwards until the mat looks clear. Greasy deposits come out with lukewarm water and a mild detergent, followed by a long rinse. Dry it at room temperature only, since heaters, heat guns and flames damage the material, and refit it dry and untreated. Sprint Filter's maintenance sheet is in the Downloads tab.

Fitment & Compatibility

For the Benelli TRK 902 Xplorer of model year 2026, one element per machine. The same T12 code is catalogued for four motorcycles: this Benelli, the Leoncino 800, and the QJ Motor SRT 800 and SRT 900. The full list is in the Fitment tab.
