Ignition Coil and Iridium Spark Plugs for Land Rover Discovery Sport (2015-2017) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2015-2017 Land Rover Discovery Sport

What it Does: Restores factory combustion efficiency, eliminates boost-onset cylinder misfires, and stabilizes engine idle across all four cylinders on the 2.0L turbocharged platform.

The Stock Discovery Sport Ignition Degradation

The compact engine bay of the transverse L550 chassis subjects ignition components to extreme thermal cycling and heat soak. Over time, factory coil-on-plug assemblies suffer dielectric insulation breakdown, micro-cracking in the primary epoxy potting, and internal copper winding fatigue. Combined with electrode erosion on aged spark plugs, this increases electrical resistance, leading to spark blowout under turbo boost, rough idle, poor fuel economy, and persistent P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This complete 4-cylinder ignition service kit features coil-on-plug assemblies built with high-conductivity internal copper windings, durable thermoplastic housings, and direct-fit blade terminals engineered to match OE electrical impedance. Paired with fine-wire iridium spark plugs, the kit delivers high dielectric strength and stable spark propagation under high-load cylinder pressures, preventing flameout and ensuring precise ignition timing.
