The G29 Z4 is one of BMW's most driver-focused machines — every detail in the cockpit should match that energy. The AutoTecknic Bright Red Audio Volume Button replaces the factory volume button with a precision-crafted red accent that adds a sharp, deliberate hit of color to the center console without disrupting the sleek, sports car character of the Z4 interior.
The finish is laser-etched rather than painted — the same method BMW uses on its OEM buttons — so the backlight shines through cleanly at night, exactly as the factory intended. In a cabin as driver-centric as the Z4's, details like this read clearly and immediately, whether the top is up or down.
Built from precision ABS plastic with a UV and scratch-resistant clear coat, this button holds up to daily use and open-air exposure without fading, chipping, or losing its finish over time. Installation is direct and tool-free — remove the OEM button, install this one, done.
For Z4 owners building out a red-accented cockpit or simply looking for one standout detail that sets their roadster apart, this is the upgrade that lands every time.
