Features and Benefits

APP-CONTROLLED, NOT REMOTE-CONTROLLED
Most valved systems ship with a garage-door-style clicker. iE's runs entirely from the iE app already on the driver's phone — one less thing to lose, one less thing to charge.


MANUAL OVERRIDE, UNLOCKED BY THE TUNE
Pair with the Pro tier of iE's B9 3.0T tune suite and take full manual control of the valves, on demand, instead of living inside a fixed factory drive-mode logic.


BUILT TO SEAL, NOT JUST BOLT ON
Engineered to the B9 S4's factory mounting points so it seals correctly and installs clean the first time — not a universal-fit compromise.
