The Audi S4 Rocker Arm transforms the rotation of the camshaft into quick and exact valve movement that allows the engine to breathe easily and strike hard upon every tap of the throttle. Since the early turbo inline-fives, the single lever of Audi performance teams has been trusted to lie at the core of numerous powerplants, from an early turbo inline-five to the highly recent supercharged V6. Within every S4 generation, the Rocker Arm has been improved to roller-tipped aluminum or full roller assemblies, slicing friction at redline, which has increased horsepower and service life. The fact that it can fit B5, B6, B7 and even the current B9 performance sedans allows owners to upgrade or replace without issue, knowing that the geometry and clearances will resemble factory geometry. The Rocker Arm raises the efficiency of combustion by reducing mass in motion and maintaining razor-sharp valve timing, thus ensuring the car consumes less fuel in everyday cruising but still provides the acceleration burst typical of a sport sedan. Reduced drag also reduces oil temperature, which protects important bearings and adds to Audi driver safety record whenever they challenge mountain roads and stop-and-go traffic. Another advantage here is noise damping; the roller tip slides between each cam lobe with a smooth motion that leaves the Audi cabin quiet even when the tachometer is rising. The component has legendary reliability, which is achieved by precision machining, heat-treated steel and needle bearings, and it has achieved this reputation during hours of high RPM testing in many countries. Since it fits directly below the cam in an overhead design, the Rocker Arm removes the need for the long pushrods, minimizes valvetrain movement, and leaves space to install Quattro hardware, which is the hallmark of all modern Audi performance models. Regardless of whether your S4 is a nineties icon or the current eight-speed edition, this mini hero makes power delivery crisp, with the commute turning into an enjoyment and proving that the nameplate still holds the compact executive standard.
