Sprint Filter P08 Air Filter for Road & Track – Aprilia Tuono V4 R APRC (2011–2015) PM01S

The Tuono V4 R took a superbike engine and removed the fairing, and the engine is what makes it. A 65-degree V4 fills its cylinders in four overlapping events rather than the two large discrete pulses of a twin, which gives the intake a smoother but far more continuous demand — there is always a cylinder drawing. That is worth knowing when you choose the element in the airbox, because the same Sprint Filter P08 PM01S also serves Moto Guzzi twins that ask for air in a completely different rhythm. It was sized for the hardest case.

Key Features

• Dry polyester medium — never oiled, nothing to migrate onto sensors in the intake
• Filtering surface roughly double that of other performance filters
• Polyester threads from ø 22 microns, woven to a calibrated aperture rather than pressed from pulp
• Direct replacement in the standard airbox — no modification, no remap
• Washable and reusable; compressed air is the normal service
• Two-year warranty from the date of purchase

Four cylinders means no gaps

On a twin the intake gets a moment between pulses. On a V4 held at high revs it does not — the demand is close to constant, and the pressure drop across the filter is therefore a continuous cost rather than an intermittent one. That is the condition in which extra filtering surface earns its keep: the element operates at a smaller fraction of its capacity for the whole of a hard run, instead of only for the first part of it.

A bike that gets used hard

Nobody bought a Tuono to potter. It gets track days, fast roads and a rider using the top half of the rev range, which loads a filter faster than the odometer suggests. This element is cleaned rather than replaced — compressed air from the clean side, refitted dry, five minutes — so the intake can be returned to its starting restriction instead of drifting permanently away from it.

Care and cleaning

Blow it through from the clean side with compressed air, working outwards. For a deeper clean, wash in lukewarm water with a mild detergent, rinse until the water runs clear, and dry fully in air — never with heat, never with a flame. Refit dry; there is no oiling step.
