Product details
This is the Airtech Executive system for the 2018 to 2019 Audi Q5 Quattro (FY). Contact KSport before ordering so fitment and options are confirmed for your car.
Assuming it fits, Executive is the fullest Airtech package. Four ride-height sensors allow automatic leveling, and a full-color OLED remote displays tank and bag pressure at all four corners and charges from a vehicle charger. A backup remote is included as well. Front upper mounts are rubber and the rear reuses the OEM top mount, details worth knowing before installation day.
The air side is a lightweight 5-gallon tank with four ports on a black carpeted board, a VIAIR 444C, a 165 to 200 psi pressure switch and two 30 A relays, with a four-corner control unit, air line, 10 mm line and power wire. Four 36-way struts with matched bags and adjustable lower mounts finish the kit, along with spanner wrenches, damping knobs and brake-line brackets. The 2015 to 2018 TT Quattro is also listed. Confirm fitment with the year, make and model checker as well.
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.
