Spark Plug – bproauto (1BP01766AA)

Spark Plug is part of the circuit that reports engine or transmission behaviour back to the control module. It is read continuously, and a value that drifts out of range sets a fault code long before the driver notices anything.

Replace the Spark Plug when the code returns after clearing, when the live data reading is out of range at operating temperature, or when the housing shows heat damage. Check the ground and the connector pins first.

This Spark Plug is listed as part 1BP01766AA (Spark Plugs & Ignition). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is BPROAUTO aftermarket stock rather than a dealer part. The OEM numbers this Spark Plug is intended to replace are stated on this page.
