This 2006 Audi S4 Avant represents a rare opportunity to own a fully built, enthusiast owned performance wagon with extensive upgrades and nearly 8,000 in recent service. Finished in black over a black leather sport interior, this S4 blends the practicality of an Avant with the performance of Audi's legendary 4.2L V8 and 6-speed manual transmission. At approximately 80,000 miles, the original engine was replaced following a track-related failure. The replacement engine had roughly 7,000 miles and was refreshed with new timing components, water pump, coil packs, oxygen sensors, and starter. Power is delivered through a belt-driven JH Motorsports Stage 1 supercharger, paired with a Stage 2 air to water intercooler, oil cooler, and upgraded fueling. Performance is further enhanced by a JHM Stage 5 clutch and lightweight flywheel, short shifter, JHM 4-1 center differential, and Wavetrac limited-slip differentials. Suspension and braking upgrades include Ohlins rear dampers, BC Racing front coilovers, 034Motorsport components, upgraded sway bars, and a JHM big brake kit, creating a confident and highly capable driving experience. Cosmetically, the S4 features subtle RS4-inspired and carbon fiber enhancements, while the interior includes carbon trim, a weighted shift knob, digital performance gauge, and upgraded infotainment for a driver-focused cockpit. Recent service totaling 7,843.72 includes a comprehensive inspection, full 75k mile service, valve cover gasket replacement, shifter adjustment, suspension repairs, sway bar and end link replacement, new front coilovers, and a four wheel alignment, ensuring this S4 is fully sorted and ready to enjoy.
