Product details
The Airtech Deluxe is a complete air suspension system for the 2002-2005 Audi A4 B6 with FWD or AWD drivetrains. It starts with four air struts carrying 36-way damping, a Viair 444C compressor, an air tank, paddle valves and a gauge, then adds two electronic switches and a wireless remote. Most owners will spend their time with that remote, which changes ride height from outside the car.
The compressor can take the car from its lowest to its maximum height in as little as four seconds, and each strut has an adjustable lower mount for fine ride-height tuning at any pressure. The included knob gives 36 damping levels on every strut. A quick-disconnect plug, all hoses, wiring and installation manuals are supplied, so the install comes down to routing the lines and wiring the compressor and relay.
Deluxe sits between the Basic paddle-valve version and the Pro Plus OLED version, so choose it when a remote matters more than a full digital display. Run the year, make and model checker before ordering, since the approved application is the 2002-2005 Audi A4. The system is also listed for 2006-2008 Audi A4 cars, and camber-adjustable top mounts are offered on certain MacPherson-strut applications.
