The facts.
DescriptionThe whole story▼
Not every 400 has one rider. Some are shared inside a household, some are hired out by the week, some spend their working life in a school with a different person on the seat every hour. A machine used that way collects wear by running time and cold starts rather than by distance, and its airbox sees far more of the year than the odometer suggests. That is the case CM267P14 is written for here — a fine medium in a bike serviced by somebody who did not choose it.
Key Features
- Dry specialist non-woven, filtration rated at 14 µm
- Rated throughput 1,800 l/m²/sec, where the woven element for this box is rated 5,050
- Stores its load through the thickness of the mat rather than across one exposed face
- Folded so that far more medium goes into the standard Triumph housing than would otherwise fit
- Dry at every stage: nothing to dose, nothing to renew, nothing that can be applied wrongly
- Cleaned and reused instead of replaced, with two years of cover from the purchase date
A part that survives being handled by strangers
Shared machines lose things. Service books go unfilled, an owner changes, and the intake tract is the one area nobody can reconstruct. A dry mat narrows what can go wrong there to almost nothing. There is no oil to measure out, so no rider can over-apply it and no film can end up downstream on a sensor. There is nothing to order in, so a busy week cannot become a missed replacement. And because the element is put back rather than binned, whoever services it is looking at the machine's actual history instead of at a fresh panel that hides it.
What the fine end is worth, and what it costs
Fourteen microns against eighty, and 1,800 l/m²/sec against 5,050: more held back, less let through, in that order and in that proportion. It is a trade rather than a promotion, and the woven element is not the poorer part — only the one drawn for cleaner air. Where a bike accumulates hours in traffic, on dry lanes or behind other vehicles, the exchange is worth making; on clean sealed roads it is not. Neither is a power part in any case. A drop-in filter leaves a standard 400 exactly as strong as it was; what it offers is a low, repeatable intake restriction on an item that is serviced rather than bought.
Care and cleaning
Direction is the one thing to get right. Compressed air goes onto the clean face and blows outwards, because a mat that holds its load in depth will bury it if the air travels the other way. When air no longer lifts anything, lukewarm water and a mild detergent flush it through; rinse until the runoff is clear. Drying happens in moving air at room temperature and by no other means — heat ruins a non-woven before the damage becomes visible. Refit dry, with nothing sprayed on.

Fitment & Compatibility
Built for the airbox of the Triumph Tracker 400 of 2026, in place of the disposable panel. The same part number answers for two further machines in Triumph's 400 range, both listed from 2024; their dates are set out in the Fitment tab.
