Ignition Coil & Iridium Spark Plugs for Jaguar XF (2013-2020) 3.0L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2013-2020 Jaguar XF

Restores optimal combustion and eliminates misfire codes by providing consistent, high-voltage spark delivery to the AJ126 3.0L Supercharged V6.

The Stock XF Ignition System Degradation

As the AJ126 engine logs mileage, the factory ignition coils are notorious for thermal degradation due to the intense heat generated by the Roots-type supercharger nestled in the engine valley. Prolonged heat soak breaks down the internal epoxy potting of the OEM coils, leading to micro-cracks in the housing. This degradation reduces voltage output, causing hesitation under boost, rough idling, and inevitable P0300-series misfire codes. Simultaneously, factory spark plug electrodes erode, widening the gap and further straining the weakening ignition coils under higher cylinder pressures.

The Engineering Solution

This ignition coil and iridium spark plug kit is engineered to withstand the extreme under-hood temperatures of the supercharged X250 and X260 chassis. The coils feature upgraded high-temperature epoxy and reinforced blade connectors to ensure stable electrical connections and prevent thermal breakdown. Paired with iridium-tipped spark plugs, which offer superior conductivity and an exceptionally high melting point compared to standard copper or platinum, this combination ensures a precise, concentrated spark. This highly efficient burn maximizes supercharger response, stabilizes idle quality, and restores factory power delivery.
