Product details
The Airtech Deluxe is the complete air system for the 1999-2005 BMW M3 E46, with four 36-way air struts, a Viair 444C compressor, an air tank, paddle valves and a gauge. Two electronic switches and a wireless remote add finer control of the paddle valves, which is what separates it from the manual setup.
Installation runs through a quick-disconnect plug: route the air lines to the box, connect four wires, then wire the compressor and relay. The remote handles ride height from outside the car, and each strut's adjustable lower mount tunes height at any pressure.
The 444C can lift the car from lowest to maximum height in as little as four seconds, and the damping knob gives 36 levels on every strut. The kit is listed for the 1999-2005 M3 and also for 3 Series E46 models in the 323i, 323Ci, 325i, 325Ci, 328i, 328Ci, 330i and 330Ci range, including wagons. Confirm your car with the year, make and model checker, and ask a technician about camber-adjustable top mounts on MacPherson-strut applications.
