Spark Plug – Mopar (SPFR8TI332)

Spark Plug converts a physical condition into a signal the powertrain module acts on. The module compares that signal against an expected range at every start-up, so a failing unit is usually logged before it becomes a driveability complaint.

Replace the Spark Plug when the fault repeats with the harness already ruled out, when resistance drifts as the part heats up, or when a connector has corroded past cleaning. Swapping a sensor to chase a wiring fault is the most common wasted repair on these circuits.

Ordering reference for the Spark Plug is part number SPFR8TI332, categorised under Spark Plugs & Ignition. Match that number against the component you are removing before you order.

The stock here is genuine MOPAR, and this Spark Plug keeps the original engineering number, which matters once a number has been superseded more than once.
