Spark Plug Set – Volvo (30650843)

Spark Plug Set 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 Set 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 Spark Plug Set in this listing carries part number 30650843 and sits in the Spark Plugs & Ignition category. The number stamped on the original part is the only reliable cross-reference.

This is VOLVO dealer-sourced stock rather than an equivalent, so the number on the Spark Plug Set traces straight back to the manufacturer.

Supplied as an set rather than as an individual component, so check that you need the whole item before ordering.
