Land Rover Part Number: WIB100030 - Secondary Air Injection Pump
WIB100030 is a Secondary Air Injection Pump fitted to Discovery 2 V8 models. It operates within the vehicle's emission control system to supply ambient air for secondary air injection during cold-start conditions, helping the catalytic converter reach operating temperature more quickly and reducing tailpipe emissions; service inspection typically covers the electrical connector, air hoses and any check valves, and replacement of the pump restores proper secondary air supply when faulty.
