Product details
Subaru Impreza WRX STI buyers from 2002 to 2004 get the Deluxe air package here, which is the approved application, with the Impreza WRX of 2002 to 2007 also listed. The parts are four struts, a single Viair 444C, an air tank, paddle valves and a gauge, and the step up from Basic is two electronic switches and a wireless remote. Check fitment with the year, make and model checker before you commit.
Electronic switches handle the paddle valves with precision, and the wireless remote lets you change height from outside the car. A quick-disconnect plug accepts the wiring, and each strut's 36 damping levels are set with the supplied knob. The 444C takes as little as four seconds to move the car from lowest to highest height.
The bags are sleeve-type or double-bellow units matched to the OEM design. Hoses, wiring and manuals come in the box, and fine tuning of the height happens at the adjustable lower mount under any pressure.
Supported features
Run the air lines to the box, connect four wires to the quick-disconnect plug, wire the compressor and relay, and you are done. The included remote adjusts ride height from outside the vehicle.
36 levels of damping adjustment on every strut using the included damping knob.
Sleeve-type and double-bellow bags engineered to match the vehicle and its OEM suspension design.
Fine-tune ride height at any pressure through the adjustable lower mount.
The single 444C can raise the car from lowest to maximum height in as little as four seconds.
Available on certain MacPherson-strut applications.
