Description
Welcome to Oz’s Garage — Bosch Fuel Injection Specialists
This listing is for a Genuine BOSCH Cold Start Valve in Premium Condition for Mercedes-Benz applications using Bosch fuel injection.
The cold start valve delivers additional fuel during cold engine starts, helping overcome fuel condensation and cold-start friction. Operating in series with the thermo-time switch, it produces an atomized swirl spray injected directly into the intake manifold/plenum for improved start-up behavior in cold conditions.
Genuine Bosch Quality — Not New, But in Premium Condition.
Each unit is carefully inspected and tested for function before shipping.
