This is a genuine OEM air vacuum valve / purge solenoid for the Jaguar S-Type fitted with the 4.2 V8 petrol engine. The solenoid controls vacuum flow within the EVAP (evaporative emissions) and intake vacuum system, helping regulate fuel vapour management and engine operation.
Manufactured to Jaguar/Denso factory specifications, this vacuum solenoid ensures correct vacuum control and communication with the engine ECU—ideal for replacing faulty, sticking, or non-functioning purge valves.
