RAPIDFIRE Spark Plug – GM (19323046)

RAPIDFIRE 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 RAPIDFIRE 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.

The RAPIDFIRE Spark Plug in this listing carries part number 19323046 and sits in the Spark Plugs & Ignition category. The number stamped on the original part is the only reliable cross-reference.

This is genuine GM stock, supplied for the RAPIDFIRE Spark Plug with the manufacturer number intact so the reference on the box matches the catalogue.
