Ignition Coil & Iridium Spark Plugs for Land Rover Discovery (2017-2020) 3.0L V6

Direct Replacement Ignition Coil & Iridium Spark Plugs for 2017-2020 Land Rover Discovery

Direct OEM Replacement: Restores factory ignition performance and eliminates misfires by delivering a consistent, high-voltage spark to the combustion chamber under forced induction loads.

The Stock Discovery Ignition Shortcoming

The Land Rover AJ126 3.0L Supercharged V6 engine generates significant under-hood thermal loads, exposing the factory ignition coils to extreme heat cycling. Over time, this thermal stress degrades the internal epoxy potting and primary/secondary windings of the OEM coils, leading to internal arcing, increased electrical resistance, and voltage drops. Concurrently, factory spark plugs experience accelerated electrode wear under supercharged cylinder pressures. These degraded ignition components commonly manifest as rough idling, hesitation under heavy throttle, poor fuel economy, and persistent P0300-series misfire codes, ultimately compromising drivability and risking unburned fuel damage to the catalytic converters.

The Engineering Solution

This direct-replacement ignition coil and iridium spark plug kit is engineered to withstand the rigorous thermal environment of the L462 chassis. The ignition coils feature upgraded copper wire windings and high-dielectric epoxy resin to prevent voltage leaks and ensure a high-energy output. The included iridium spark plugs utilize an ultra-fine wire center electrode, requiring less voltage to jump the gap while providing a highly focused, intense spark for complete combustion. The iridium alloy construction offers exceptional resistance to spark erosion and corrosive combustion gases, extending service intervals well beyond standard copper or platinum plugs. Blade-style terminals with an OEM-spec female connector guarantee a secure, weather-tight integration to the factory wiring harness with zero voltage drop.
