The Bilstein B4 OE Replacement (DampTronic) front twin-tube strut is a direct OE-style replacement for the electronically adjustable dampers on many European vehicles, including 2006–2013 Porsche 911 Carrera 4S. It preserves original ride quality while meeting or exceeding OE standards, restoring intended comfort, handling and safety with Bilstein testing and OE-equivalent design.
