The facts.
DescriptionThe whole story▼
Four media exist for this airbox, and no single machine is offered all four. The Crossfire/X is listed with the standard weave, with this 14-micron mat and with the racing weave; the Gaokin that shares the housing is listed with the standard weave, the racing weave and the 7-micron nonwoven instead. The hardware does not split that way — the price list does. Reading a fitment list with that in mind saves a good deal of guessing.
Key Features
- Dry special nonwoven filtering at 14 microns, rated at 1,800 l/m²/sec
- Depth filtration: particles are held inside the mat, not only on its face
- Never oiled — dry when supplied, dry when refitted after every wash
- Drops into the standard Crossfire/X airbox; no cutting, no adapter, no remap
- Priced below the standard woven element in this same housing
- Washable and reusable, with two years of warranty from the purchase date
What the catalogue is and is not saying
A fitment list is a record of what the manufacturer has released and tested for a given machine, not a statement about physics. When a medium appears for one badge in a shared housing and not for another, the honest reading is that the row is the commitment: order the one that names your bike and its years, and treat the rest as somebody else's row. On this page that row is the Brixton Crossfire/X of 2017 to 2026, and everything below describes CM136P14 in that machine.
What 14 microns costs and buys
Against the 80-micron weave in the same box, this mat passes roughly a third of the rated flow — 1,800 against 5,050 l/m²/sec — and holds a great deal more of what is suspended in the air. That is a trade and not a ranking: the finer medium is not the better one, only the one drawn for harder air, and the flow it gives up is given up on clean days as well as dusty ones. It is the right choice where dry gravel, farm tracks and dust behind other vehicles are the normal working environment rather than an occasional afternoon. And it is not power: in an unmodified airbox this element leaves a standard Crossfire/X exactly as strong as it was.
Care and cleaning
The CM136P14 is loaded through its depth, so it is cleaned patiently. Compressed air on the clean face, worked outwards, lifts the bulk of it; lukewarm water with a mild detergent takes what remains, rinsed until the water runs off clear. Drying is done in moving air at room temperature and by nothing else — heat guns and radiators ruin the nonwoven before any change is visible. Refit it dry, with nothing applied. The maintenance sheet is in the Downloads tab.
Fitment & Compatibility
Made for the Brixton Crossfire/X of 2017–2026, seated in the series airbox without modification. This 14-micron code is listed for that machine alone, while the standard weave for the same housing covers three. Confirm your build year in the Fitment tab.
