Product details

The Airtech Basic air suspension for the 2006-2008 Audi A4 B7 is a complete system for FWD and AWD cars. It is built around four application-specific air struts with 36-way damping and adjustable lower mounts, with a Viair 444C compressor, a 5-gallon black steel tank and manual paddle valves completing the setup. The page also lists the 2002-2005 Audi A4 B6 FWD and AWD as compatible applications.

The paddle valves control the front and rear bags, and a dual-needle 200 psi gauge sits beside the switches so pressure is always visible. The compressor can raise the car from lowest to maximum height in as little as four seconds, and the page gives 4-7 seconds for Basic and Deluxe. Height range is listed as 0 to 120/200 mm depending on the vehicle.

The damping knob is included, with softer damping turned counterclockwise and stiffer clockwise across 36 levels. All hoses, wiring and installation manuals come in the kit. The page recommends professional installation, a recheck after the first 500 miles or one month, and a leak check at 70 psi with soapy water on each fitting. Deluxe, Pro Plus and Executive are separate part numbers if you want electronic remote control or height sensing. Use the year, make and model checker to confirm fit before ordering.

Supported features
36-Way Adjustable Damping

36 levels of damping adjustment let you dial in the air struts. Insert the included damping knob and turn softer (counterclockwise) or stiffer (clockwise).

High-Quality Air Bags

Air bags are engineered to match the vehicle. Sleeve-type and double-bellow bags are used depending on the OEM suspension design.

Adjustable Lower Mounts

Like KSport coilovers, the struts allow fine-tuning of ride height at any pressure through an adjustable lower mount.

Viair 444C Compressor

Chosen for reliability and performance; the single 444C can raise the car from lowest to maximum height in as little as four seconds. Airtech Basic and Deluxe raise in 4–7 seconds; Pro Plus and Executive raise faster, in 2–5 seconds.

Manual Paddle Valves & 200 psi Gauge

Paddle valves control front and rear bags; the dual-needle gauge mounts beside the switches so pressure is always visible.

Camber-Adjustable Top Mounts

Camber-adjustable top mounts can be added on certain MacPherson-strut applications.
