Sprint Filter P08 Air Filter for Road & Track – QJ Motor SRT 700 / X (2024–2026) SM258S

The fitment list for this element names two motorcycles wearing two different badges, and the Benelli among them has been in production a year longer than the SRT 700. Neither detail is trivia. Benelli and QJ Motor build on shared platforms, so the airbox behind the SRT’s tank is not a one-model item: it is a component with two model lines feeding it and a service history that began before this motorcycle reached the showrooms. For an owner that translates into something plain and welcome — the intake part on this page is a mainstream product rather than an orphan.

Key Features

• Single-layer dry polyester weave, 80 microns, rated at 5,050 l/m²/sec
• 93.13 % of 100-micron particles retained in the manufacturer’s comparison
• One part number for the SRT 700, the 700 X and their Benelli counterpart
• Slots into the untouched series airbox; nothing cut, nothing recalibrated
• Around twice the filtering area of a conventional performance element
• Dry from new, never oiled, two-year warranty from the date of purchase

What a shared part number is evidence of

Engineering rather than marketing. An element is drawn to a sealing face and a depth, so two machines take the same panel when they were designed around the same box, and the badge on the tank gets no vote. Two consequences are worth naming. Ordering is done by housing and model year rather than by model name, which is why the year matters more than the letter after it. And a part carried across two ranges tends to stay obtainable for longer than one tied to a single nameplate, which is not nothing on a young marque.

What the standard weave is and is not

It is the medium designated for road and track use: 80 microns of aperture against 5,050 l/m²/sec of rated flow, the balanced middle of a range whose finer media hold more and pass less. It is not a power part. A drop-in filter does not make a standard SRT 700 noticeably stronger, and any listing implying otherwise has changed the subject. What it does is start the intake restriction low and, more to the point, put it back there at every cleaning instead of letting it climb until a new panel is bought.

Care and cleaning

Use compressed air from the clean side and let the trapped material exit by the route it entered; at sensible intervals that is the entire maintenance. Where the cloth has picked up something greasy, lukewarm water with a little mild detergent lifts it, and the rinse continues until the water leaves clear. Ambient air does the drying — never a heat gun, a radiator or a flame — and the SM258S is refitted dry, with no oil of any kind involved. Its maintenance sheet sits under the Downloads tab on this page.

Fitment & Compatibility

For the airbox of the QJ Motor SRT 700 and SRT 700 X, model years 2024 to 2026, one element per machine. The same code serves a Benelli, two motorcycles in total; confirm your year in the fitment list.
