Audi S4 Alternator

The Audi S4 Alternator is a miniature power station that converts engine movement into reliable electricity and keeps all systems running whether you are speeding along a back road or crawling in traffic. Constructed within a rigid two-piece aluminum shell, this Audi Alternator has a shaft-mounted rotor, stator windings, an internal cooling fan, and a fine voltage regulator that combine to maintain consistent current flow even during stereo pounding and heated seat overload. The reliability of this product is attributed to the presence of twin sealed bearings that remain smooth even at high RPM, in addition to silicon rectifier diodes that absorb heat, thereby letting the driver experience spirited performance from the S4 without having to worry about dimmed lights or poor start-ups. This means that compatibility spans all generations of the Audi performance sedan, Avant, and Cabriolet, so your S4, whether it is a twin-turbo V6-powered model or equipped with the updated turbocharged 3.0-liter engine, is compatible, provided it is properly installed, aligned with the crank belt, and interfaced with the new Powertrain Control Module for finer adjustments of voltage control. It can control the strength of the field within milliseconds, which reduces unwarranted drag on the engine and reduces fuel consumption, while at the same time ensuring that all the highly important safety mechanisms of the car, including ABS, stability control, and adaptive headlights, are powered by a steady supply of rock-solid power on every Audi. Another technology applied on this Alternator is the self-cooling fan cut into the front pulley, forcing air through finned vents that cool the Alternator down without thermal fade during track days, and the smart regulator ensures that the Alternator does not overcharge and damage sensitive onboard electronics. These excellent features make the component rise above the stiff car market competition, demonstrating how Audi incorporates durability and performance focus into each of the supporting components.
