Ignition Coil and Iridium Spark Plugs for Land Rover Discovery Sport (2018-2023) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2018-2023 Land Rover Discovery Sport

What it Does: The complete ignition kit restores factory spark energy and precise combustion timing on the 2018-2023 Discovery Sport to eliminate misfires, rough idling, and hesitation under boost.

The Stock Land Rover Discovery Sport Ignition Coil & Plug Breakdown

The turbocharged Ingenium 2.0L inline-four operates under extreme cylinder pressures and elevated thermal loads. Over extended heat cycles, the factory coil-on-plug epoxy insulation degrades, creating internal micro-arcing and secondary winding breakdown. Concurrently, factory spark plug gaps widen from standard electro-erosion, elevating the required firing voltage beyond what aged coils can deliver. In the L550 chassis, this degradation triggers intermittent cylinder misfires (P0300–P0304 DTCs), fuel trim drift, unburned hydrocarbon catalytic fouling, and sudden power derating under moderate-to-heavy load.

The Engineering Solution

This comprehensive service kit replaces fatigued ignition hardware with four high-dielectric pencil coils and matching fine-wire iridium spark plugs. The ignition coils feature heat-resistant thermoplastic housings, copper core windings, and high-temp silicone boots to prevent high-voltage blow-by. Paired with laser-welded iridium electrode spark plugs, this setup maintains consistent spark gap geometry and low firing voltage demand even under peak boost, ensuring rapid flame kernel propagation, zero spark blowout, and OE-grade dwell time stability.
