Sprint Filter P08 Air Filter for Road & Track – Triumph Trident 800 (2026) SM301S

“Designed to last the life of the motorcycle” is an odd sentence to read on a part for a machine that has no life behind it yet. The Trident 800 appears in this catalogue with a single model year against it, and there is no worn example anywhere to reason from — no accumulated experience of what its airbox collects, no consensus about intervals, nothing but the housing and what goes in it. That is worth being honest about, because it changes what the promise actually means.

Key Features

• Dry woven polyester in one layer: 80 µm, 5,050 l/m²/sec
• Never oiled, so there is no dose to get wrong and nothing to travel onto the sensors
• Replaces the paper panel in the standard airbox — no cutting, no remap
• Roughly double the filtering area of the usual performance element
• Sprint Filter measured 93.13 % retention of 100-micron particles; four-layer oiled cotton reached 76.42 %
• Serviced with compressed air rather than replaced, and covered for two years from purchase

A promise about the part, not a forecast about the bike

Service life claims usually rest on a fleet of high-mileage examples. Here there is none, and the claim has to be read for what it is: a statement about a woven polyester element that is cleaned rather than consumed, not a prediction about how this particular motorcycle will age. That is a narrower promise, and it happens to be the one that matters. Whatever the Trident 800 turns out to demand of its intake, the element will still be a part you clean.

Specify from the airbox

With no service history to lean on, the sensible basis for choosing is the hardware and the roads you ride, not received wisdom that does not exist yet. Nor is there a power argument to fall back on: an insert filter does not make a standard Trident 800 quicker, and no honest description of one will tell you otherwise. What the SM301S changes is where the intake restriction starts and how far it drifts before you reset it — and on a machine nobody has long-term data for, being able to look inside and see for yourself is worth more than usual.

Care and cleaning

Blow the SM301S through from the clean side outwards with compressed air; that is the whole of a routine service. Anything greasy comes out with lukewarm water and a mild detergent, rinsed until the water runs clear. It dries in open air — heat guns, radiators and flame all ruin polyester — and goes back in dry and untreated. The Sprint Filter maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

The P08 element for the Triumph Trident 800, model year 2026. The Tiger Sport 800 of 2025 to 2026 shares the same airbox and the same part. The 660 Trident is a different machine with a different element, so check displacement and model year when ordering.
