Product details
The Airtech Executive is the top management tier for the 2002 to 2004 Subaru Impreza WRX STI, and the difference is in the brains. Four ride-height sensors feed a four-corner electronic control unit that levels the car automatically, while a full-color OLED remote shows tank pressure and the pressure at all four corners. A separate backup remote and a vehicle charger for the main remote are in the box, so you are never stuck without a way to move the car.
Lifting comes from one VIAIR 444C compressor with a 165–200 psi pressure switch and two 30 A relays, feeding a 5-gallon lightweight tank with two 1/4 in and two 3/8 in ports on a black carpeted board. You also get 25 m of 1/4 in air line, 1 m of 10 mm line, power wire, fittings, a tool kit with spanner wrenches, damping knobs and brake-line brackets, and the owner's manual. Struts carry 36-way damping. Raise time depends on plumbing and installation, so ask a technician about your build and verify fitment before ordering.
Supported features
The OLED color-screen remote displays tank and bag pressure at all four corners and charges from the included vehicle charger. A standard 4-button backup remote is included.

Fine-tune ride height at any pressure through the adjustable lower mount.
One VIAIR 444C compressor, a 165–200 psi pressure switch and two 30 A relays are included. Raise time depends on the vehicle, plumbing, pressure and installation.
