Sprint Filter P08 Air Filter for Road & Track – Yamaha YZF-R7 (2021–2026) CM148S

More YZF-R7s see a circuit than any other bike on this platform, and a large share of them run in production or clubman classes where the rulebook is short and strict. Those rules tend to protect the airbox, the throttle bodies and the ECU map, while leaving the filter element itself open — it is one of the few intake changes a stock-class machine is allowed to make. The Sprint Filter P08 CM148S fits that gap precisely: the standard airbox stays, the standard lid closes, and the part that changes is the one inside.

Key Features

• Practical between sessions, because compressed air cleans it in minutes
• A dry P08 polyester medium, never oiled, with nothing to reach the sensors or the intake tract
• Filtration at 80 microns; airflow of 5,050 litres per square metre per second
• Filtering surface roughly double what other performance filters carry
• Standard airbox, direct replacement, no modification and no remap
• Two years of warranty run from date of purchase

A track day is a filtration day

A circuit looks clean and is not. Rubber dust, brake dust, hot dry air pulled off a surface that thousands of laps have polished — a bike takes in far more air per hour on track than it ever does on the road, and it takes it in at wide throttle where the airbox is working hardest. An element that was fine on Friday can be visibly loaded by Sunday. A dry filter can be lifted out in the paddock, blown through from the clean side and refitted before the next session, which means the machine goes out in the afternoon in the same intake condition it had in the morning.

Repeatability is the point, not peak power

A drop-in element does not turn a standard R7 into a faster motorcycle, and treating it as a power part sets the wrong expectation. What it offers a rider who is chasing lap time is a variable removed. Fuelling and throttle response depend on the pressure the engine sees behind the filter; if that pressure drifts as the element loads, then the bike is subtly different at the end of the day from the one that was set up in the morning. Restoring the element to its starting condition restores the baseline. On a machine where the rider is trying to change one thing at a time, that is worth more than a claim.

Care and cleaning

Compressed air on the clean side, blown outwards, is the normal service and the one to reach for in the paddock. A deeper clean calls for a wash in lukewarm water with a mild detergent, rinsing until the water runs clear, and a full dry in open air — never with heat, never with a flame. The element is refitted dry, with no oiling step to remember. The Sprint Filter maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

Made for the Yamaha YZF-R7, 2021 to 2026. The same CM148S element serves seven machines that share this airbox, including the MT-07, FZ-07, XSR 700, Tracer 7 and the XTZ 690 Tenere; the complete list is in the Fitment tab.
