2008 Audi S4 Avant 6-Speed

This 2008 Audi S4 Avant is one of a reported 156 examples that were equipped with a six-speed manual transaxle for the model year, and it is powered by a replacement 4.2-liter V8 that was installed under current ownership. Finished in Dolphin Gray Metallic over black Silk Nappa leather with Silver Alcantara inserts, the car has been modified with revised engine management software, an RS4-specification clutch and flywheel, a JHM intake manifold and headers, a Hotchkis rear anti-sway bar, and KW coilovers. Additional equipment includes a Torsen torque-sensing center differential, a Quattro all-wheel-drive system, the Convenience Package, a sunroof, replacement xenon headlights, fog lights, a rear spoiler, 18″ double seven-spoke alloy wheels, heated power-adjustable Recaro front seats, a Bose sound system, Audi Navigation Plus infotainment, and a six-disc CD changer. The car was registered with two owners in Florida and Texas before it was acquired by the current owner in 2019, and it now has 118k miles. This B7 S4 is now offered on dealer consignment with partial service invoices, a clean Carfax report, and a clean Colorado title. Dolphin Gray Metallic paint finishes the exterior, and further details consist of a sunroof, replacement xenon headlights, fog lights, a rear wiper, a rear spoiler, silver-finished mirror caps, and quad exhaust outlets. The rear bumper cover has been repainted, and paint chips are noted on the front bumper cover and on the roof ahead of the sunroof. The 18″ double seven-spoke alloy wheels are mounted with 235/40 Michelin Pilot Sport 4S tires that show 2021 production codes. The car was fitted with KW V3 coilovers and a Hotchkis rear anti-sway bar in 2020, and the power steering reservoir and hose were replaced in September 2024. Stopping power is provided by four-wheel disc brakes with ventilated front rotors. The heated power-adjustable Recaro front seats are upholstered in black Silk Nappa leather with Silver Alcantara inserts, and carbon-fiber trim accents the cabin. Interior appointments include a Bose sound system, Audi Navigation Plus infotainment, a six-disc CD changer dual-zone automatic climate control, and cruise control. The Alcantara on the driver’s seat is worn. A replacement leather-wrapped multifunction steering wheel was reportedly installed in 2019, and it sits ahead of a 170-mph speedometer, an 8k-rpm tachometer, a TFT driver information screen, and auxiliary gauges for coolant temperature and fuel level. The digital odometer indicates 118k miles, approximately 3k of which were added under current ownership. The replacement 4.2-liter DOHC V8 was sourced from Audi, and it was installed in 2019 by Elevation Motors of Lakewood, Colorado. Additional work in 2019 included the installation of revised engine management software, a JHM intake manifold and headers, an RS4-specification flywheel and clutch, and a replacement EGR valve, clutch slave cylinder, and driveshaft. The fuel level sending unit, pump, and tank were replaced in 2020, and service in September 2024 included replacing the radiator in addition to the AC receiver drier, compressor, condenser, pressure switch, control assembly, and hose seals. Power is routed to all four wheels through a six-speed manual transaxle and a Quattro all-wheel-drive system with a Torsen center differential.
