The Street Cup gets used in short, sharp bursts — out of a roundabout, up to the next one, hard on and hard off — and that is exactly the kind of riding in which intake restriction shows up. Not at peak power, which this motorcycle rarely visits, but in the transient: the fraction of a second between the throttle opening and the engine having the air it just asked for. The Sprint Filter PM174S is a dry polyester element that starts at a low restriction and is washed back to it, instead of drifting upwards between services.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe standard airbox takes it as it is: no modification, no remap, no paperwork\u003c\/li\u003e\n\u003cli\u003e80 µm of filtration at 5,050 l\/m²\/sec — the standard P08 medium, made for road and track\u003c\/li\u003e\n\u003cli\u003eDry woven polyester with no oil in it, so there is nothing that can migrate downstream\u003c\/li\u003e\n\u003cli\u003eAbout double the filtering surface you would get from another performance filter\u003c\/li\u003e\n\u003cli\u003eWashable and reusable, and built to stay with the motorcycle for as long as it lasts\u003c\/li\u003e\n\u003cli\u003eTwo years of warranty from the day it is bought\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eResponse is a transient, not a peak\u003c\/h2\u003e\u003cp\u003eEvery measurement that sells air filters is taken at wide open throttle, held steady. Almost no road riding happens there. What a rider on a café-racer-shaped Bonneville notices instead is how quickly the engine answers a small opening of the throttle in the middle of the rev range, and a restriction in the intake tract blunts that before it costs anything on a dyno. The P08 does not add power to a standard engine — that claim is not honest — but it keeps the resistance the engine is pulling against low, and it keeps it there over the whole service interval.\u003c\/p\u003e\u003ch2\u003eThe change nobody has to notice\u003c\/h2\u003e\u003cp\u003eThe Street Cup was bought for how it looks, and most owners are careful about what they hang on it. This one is invisible: the element sits inside the standard airbox, the cover goes back on unmodified, the fuelling is unchanged and there is nothing to declare.\u003c\/p\u003e\u003ch2\u003eCare and cleaning\u003c\/h2\u003e\u003cp\u003eOn a bike that mostly sees dry roads, an air line is the entire maintenance plan: aim it at the clean side, work outwards, and the element is back at the restriction it started with. Everything beyond that is a wash — lukewarm water, a mild detergent, rinsing until the water runs clear. Let it dry right through in open air afterwards; heat and flame are out, and so is any kind of oil. Refit the PM174S dry. The maintenance sheet is in the Downloads tab.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eMade for the Triumph Street Cup, 2017–2026. The same PM174S element covers five machines built around this airbox — the Bonneville T100 and T120, the Street Cup, the Street Scrambler and the Street Twin.
