Ignition Coil & Iridium Spark Plugs for Jaguar F-Pace (2017-2020) 3.0L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2017-2020 Jaguar F-Pace

Restores ignition efficiency and eliminates misfires: Direct-replacement ignition coils and iridium spark plugs designed to ensure complete combustion, stable voltage output, and reliable spark under high supercharged engine loads.

The Stock F-Pace AJ126 Ignition Limitations

The supercharged 3.0L AJ126 V6 generates significant under-hood temperatures, leading to accelerated thermal degradation of the factory ignition coil epoxy and internal windings. Over time, severe heat soak compromises the primary and secondary coil resistance, resulting in weak spark energy, rough idling, hesitation under boost, and eventual P0300-series misfire codes. Furthermore, standard platinum or severely worn OEM spark plugs naturally widen in gap, excessively increasing the voltage demand and causing premature coil pack failure.

The Engineering Solution

This ignition coil and iridium spark plug kit addresses these thermal limitations by utilizing high-dielectric epoxy and advanced copper wire winding patterns to maximize thermal conductivity and prevent internal arcing. The coil housing is constructed from heat-resistant polymers that withstand the aggressive thermal cycling inherent to the F-Pace engine bay. Paired with ultra-durable iridium-tipped spark plugs featuring a finely welded center electrode, the system significantly lowers the voltage requirement for spark propagation while resisting spark erosion.

This mechanical synergy ensures consistent arc duration, complete fuel burn, optimized throttle response, and robust defense against high-rpm spark blowout.
