Ignition Coil & Iridium Spark Plugs for Jaguar XE (2017-2019) 3.0L V6

Direct-Fit Ignition Coil & Iridium Spark Plugs for 2017-2019 Jaguar XE

Restores critical spark delivery and combustion efficiency: This direct replacement ignition coil and iridium spark plug kit resolves misfires and erratic idling in the supercharged 3.0L V6.

The Stock XE Ignition System Vulnerabilities

The OEM ignition coils on the supercharged AJ126 engine are subjected to intense thermal stress due to their proximity to the forced-induction components and the tight confines of the X760 engine bay. Over time, continuous heat cycling degrades the internal epoxy resin and primary/secondary copper windings, increasing electrical resistance. This degradation leads to weak spark output, unburnt fuel, and notorious cylinder misfires under heavy load. Simultaneously, factory spark plug electrodes wear down, widening the plug gap and further straining the ignition coils, resulting in sluggish throttle response, increased emissions, and potential catalytic converter damage if left unchecked.

The Engineering Solution

This comprehensive replacement kit tackles the root causes of supercharged ignition failure by utilizing upgraded materials built to withstand excessive heat soak. The ignition coils feature high-grade dielectric epoxy and reinforced copper windings that ensure consistent voltage multiplication, eliminating the resistance drops seen in aging OEM units. Matched with premium iridium spark plugs, which boast an ultra-fine center electrode and superior melting point compared to standard platinum or copper plugs, this setup guarantees a precise, concentrated spark. The iridium construction prevents premature gap expansion, ensuring reliable cold starts and sustained power delivery across the entire RPM range, maintaining optimal volumetric efficiency for the supercharged V6.
