Overview. The 1985 California cars with a trap oxidizer need a different BVX valve layout from other W123s due to the heat shield forward of the firewall. The BVX-CA replaces the original Bosch monovalve with a reliable unit.
Features
- Vehicle-specific, drop-in replacement: mounts to the original brackets, hoses and electrical connector
- Reliable at high engine RPM and in extreme temperatures, where Bosch valves stick
- Built with technology from late-model vehicles
Fitment
- 1985 300D, 300CD, 300TD with California emissions / trap oxidizer only
- All other W123: order the BVX-1 model
