Ignition Coil & Iridium Spark Plugs for Jaguar XE (2019) 5.0L V8

High-Performance Ignition Coil & Iridium Spark Plugs for Jaguar XE

Direct replacement ignition coils and high-performance iridium spark plugs designed to restore optimal combustion and eliminate misfires on the supercharged 5.0L V8.

The Stock XE AJ-V8 Ignition Degradation

The factory ignition system on the Jaguar AJ133 supercharged 5.0L V8 is subjected to extreme thermal stress and high cylinder pressures. Over time, the OEM coil packs degrade due to heat soak, leading to increased internal resistance and weak voltage output. Similarly, standard or worn spark plugs suffer from gap widening and electrode erosion. This combination often results in hesitation under heavy load, rough idling, incomplete combustion, and dreaded cylinder misfires that can trigger limp mode or catalytic converter damage.

The Engineering Solution

This 16-piece complete ignition overhaul kit provides a robust mechanical upgrade over aging factory components. The included ignition coils feature high-temp epoxy resin and heavy-duty copper windings to deliver a consistent, high-energy spark, combating heat saturation within the cramped X760 engine bay. Paired with high-performance iridium-tipped spark plugs featuring a durable nickel core, this kit ensures exceptional wear resistance and a highly concentrated spark kernel. The 12mm thread diameter and 28mm reach perfectly match the AJ-V8 cylinder head specifications, ensuring stable voltage transfer between 3-12KΩ. The precision iridium tip requires less firing voltage, which reduces the load on the ignition coils while ensuring reliable ignition under high-boost conditions.
