Sprint Filter P08 Air Filter for Road & Track – Triumph Tracker 400 (2026) CM267S

The catalogue gives this machine a single model year. Its two housing-mates have been listed since 2024; the Tracker 400 appears for 2026 and nothing earlier, the shortest entry Triumph has on this airbox. For a component drawn around one season that would be a supply question worth asking early. Here it is not, and the reason matters more than the reassurance: CM267S is dimensioned to a housing, not to a model name.

Key Features

• Woven polyester in a single layer, run dry — no oil on delivery, none after any cleaning
• Rated at 80 microns of filtration and 5,050 l/m²/sec of throughput
• The 22-micron figure for this cloth is the thread diameter, never the size of the openings
• Takes the paper panel's place in the untouched series box: nothing trimmed, no fuelling work
• Roughly double the filtering area a comparable performance element brings to this box
• Serviced and refitted rather than repurchased; built to last the machine, warranted two years

Why a short model window does not shorten supply

Consumables are the awkward part of owning a single-season machine. Small volumes decide what a distributor keeps on a shelf, and that logic governs bodywork and anything else cast with a model code on it. It does not govern this element, because the element is not the Tracker's — it belongs to the airbox. Three machines from Triumph's 400 range breathe through the same box against the same number, and two have been on sale since 2024. Fit it once and the question closes altogether: a washable panel is bought a single time, so availability stops being the owner's problem rather than merely being postponed.

Eighty microns, read properly

Media trade retention against flow in both directions, and neither direction wins. A tighter weave stops more and passes less; an opener one reverses both. This one sits at 80 microns and 5,050 l/m²/sec, rather than at either extreme, and in Sprint Filter's own comparison it held back 93.13 per cent of 100-micron particles where four-layer oiled cotton managed 76.42. What it will not do deserves saying without hedging: a drop-in element does not make a standard 400 single noticeably stronger. The gain is duller — an intake resistance that begins low and is returned there at every service, instead of climbing until somebody orders a replacement.

Care and cleaning

An air line held against the clean inner face and worked outwards sends the dirt back along the path it arrived on. Where a season has left more than air will lift, lukewarm water with a mild washing-up liquid finishes it; rinse until it runs clear and leave it in moving room air. Heat distorts the weave, so radiators, heat guns and flame are out, and the panel goes back dry. Nothing is applied afterwards, so there is no oiling step. The maintenance sheet is in the Downloads tab.

Fitment & Compatibility

Catalogued for the Triumph Tracker 400 of 2026. Two further machines in Triumph's 400 range share this airbox and this number, both listed from 2024; the Fitment tab gives each its own year span, so check yours before ordering.
