The facts.
DescriptionThe whole story▼
A flow figure is a rate, and a rate only counts for as long as it is drawn. That is the honest place to start with a racing element on an unfaired roadster. The MT-10 has no bodywork to hide behind, so the stretches where its engine asks for everything available are counted in seconds rather than minutes, and the rider is the thing standing in the wind. The Sprint Filter SM238S F1-85 is rated at 15,000 l/m²/sec — close to three times the airflow figure of the standard P08 from the same housing, for the seconds when that is the question, and a cloth that asks to be checked more often for every second when it is not.
Key Features
- Dry polyester racing medium woven from threads of 22 microns and up
- Rated flow of 15,000 l/m²/sec against 5,050 for the P08 in the same airbox
- Retention of 95.22 per cent against 100-micron particles, measured by Sprint Filter
- Direct replacement for the original element, with the airbox left as it is
- Dry from end to end: restored with compressed air, never oiled
- Designed for the life of the motorcycle and warranted for two years from purchase
How much of a ride is spent at full demand
On a closed circuit an MT-10 can be held in the upper half of its rev range lap after lap, and there the flow rating finally has somebody to spend it. On a road the same engine reaches that band in short bursts between corners and limits, and an upright machine without bodywork reaches it for less time than a faired one does. None of that is an argument against the element; it is an argument about who it is for. A rider who books track days repeatedly is buying capacity that gets used. A rider who does not is buying capacity that sits there.
The other half of the trade
The racing cloth is not a coarser P08, and the figures are more interesting than they look: at 100 microns it holds back more than the P08 does, 95.22 per cent against 93.13. The 85 in its name is not a pore size, and no comparison is published for the finest dust — which matters, because road air carries it every second the engine runs, while the flow advantage applies only near the limiter. The part also costs a little over twice what the P08 does in this size. Circuit air is swept; road air is not. Neither element makes a standard MT-10 stronger, so the decision is about which risk you would rather carry.
Care and cleaning
Compressed air from the clean side outwards is the whole routine between sessions, which is precisely why racing media are dry: it takes a minute in the paddock and needs nothing carried in the van. Where the element is genuinely dirty, lukewarm water with a mild detergent and a thorough rinse will do it, followed by air drying until it is dry right through — no heat source, no flame, and never refitted damp.
