Sprint Filter PM209S F1-85 air filter

The facts.

DescriptionThe whole story▼

Set the two specifications side by side and one reads like a misprint. This element is rated to pass 15,000 l/m²/sec, where the standard woven panel for the same 550 cc Tornado airbox, an 80-micron cloth, passes 5,050 — three times the air, which you would expect to be paid for in filtration on the part that costs a multiple. Then read the measured retention: 95.22 % of 100-micron particles for the F1-85, against 93.13 % for the standard weave. Both figures are published, neither cancels the other out, and seeing why is most of what there is to understand.

Key Features

  • Dry woven polyester, supplied without oil and never given any afterwards
  • Polyester threads from 22 µm, rated at 15,000 l/m²/sec, the fastest medium in the range
  • Retention measured at 95.22 % of 100-micron particles, against 93.13 % for the P08
  • Made for the airbox of the 550 cc Benelli Tornado, model years 2025–2026
  • Roughly twice the filtering fabric of other performance elements, in the series frame
  • Serviced with compressed air, refitted, and warranted for two years from purchase

A rating and a measurement answer different questions

The flow figure describes the medium: how much air a square metre of the weave passes. The percentage describes an outcome — how much of a population of particles at one stated size, here 100 microns, a test found held back. The 85 in the name is no aperture at all: the F1-85 is a different weave, of polyester threads from 22 µm in diameter, and that construction rather than a bigger opening is what lets it pass more air and still hold back more in that test. Read as a pair on the 550 cc Tornado's airbox they say something worth knowing: the higher flow did not produce the worse result in the test that was run. Read separately, either one misleads.

The figure that really separates them

It is the flow rating. 15,000 l/m²/sec against 5,050 for the standard panel in the same 550 cc airbox is close to three times the throughput, and delivering that is what this cloth exists for — a racing specification, catalogued as one. What it asks in return deserves saying plainly: Sprint Filter lists it at close to three and a half times the standard element for this airbox, which is the clearest statement available of who it was drawn for. And it will not make a standard 550 cc Tornado noticeably stronger. No slot-in element does that, whichever weave sits in the frame.

Care and cleaning

Compressed air, held to the clean face and worked outwards, is the routine — the trapped load leaves the weave along the path it entered by. A film that air will not shift comes away under hand-warm water with a little mild detergent, rinsed until nothing further leaves the cloth. Drying is ambient and unhurried, because heat is what damages polyester: no hot-air gun, no radiator, no flame. The PM209S F1-85 returns to the box dry and untreated, and the maintenance sheet is under Downloads.

Fitment & Compatibility

Made for the airbox of the Benelli Tornado with 550 cm³, built in 2025 and 2026 — capacity and year are both part of the fitment. Five machines in total take this racing code, across Benelli and QJ Motor; the full list is in the Fitment tab.
