Ignition Coil & Iridium Spark Plugs for Land Rover Range Rover Sport (2010-2013) 5.0L V8

High-Output Ignition Coil & Iridium Spark Plug Kit for 2010-2013 Jaguar XF

Replaces the factory ignition coils and spark plugs to restore optimal spark delivery, eliminate misfires, and improve combustion efficiency.

The Stock XF Thermal Degradation Issue

The OEM ignition coils on the X250 chassis are notorious for premature thermal degradation due to their placement directly above the exhaust manifolds and within the tight confines of the 5.0L AJ-V8 engine bay. Over thousands of severe heat cycles, the internal epoxy resin and secondary copper windings begin to break down. This structural degradation leads to increased electrical resistance, internal voltage leaks, and a weaker spark. Symptoms typically manifest as hesitation under heavy throttle, rough idling, worsening fuel economy, and eventually P0300-series misfire codes as the factory spark plugs widen their gap and demand more voltage than the failing coils can supply.

The Engineering Solution

This comprehensive ignition service kit combines OE-plus specification coil packs with advanced iridium-tipped spark plugs to address factory ignition shortcomings. The new coils feature an upgraded high-dielectric epoxy injection and premium-grade heavy-duty copper wire internals, significantly reducing internal resistance while maximizing heat dissipation. By reinforcing the primary and secondary windings, these coils maintain a consistent voltage output even under extreme engine bay heat soak conditions. Paired with the ultra-fine center electrode of the included iridium spark plugs, the system requires less voltage to bridge the spark gap while generating a hotter, more stable spark front. This translates to complete combustion, a stabilized idle, and restored throttle response.
