Ignition Coil and Iridium Spark Plugs for Land Rover Defender 110 (2022-2023) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2022-2023 Land Rover Defender 110

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces worn factory ignition components on the 2022-2023 Defender 110 to eliminate spark blowout, stabilize idle, and restore peak combustion efficiency under boost.

The Stock Land Rover Defender 110 Ignition Breakdown and Thermal Stress

The L663 chassis running the turbocharged direct-injected Ingenium AJ200P engine subjects factory ignition components to severe underhood temperatures and high cylinder pressures. Over operational cycles, thermal degradation compromises the internal epoxy potting and copper primary windings of the OEM pencil coils. This breakdown leads to insulation failure, micro-arcing, intermittent hesitations, and cylinder misfire codes (P0300–P0304). Simultaneously, rapid electrode erosion on factory plugs widens the gap, increasing the secondary voltage demand and over-stressing the coils under heavy throttle.

The Engineering Solution

This comprehensive service kit replaces factory components with heavy-duty pencil ignition coils and fine-wire iridium spark plugs designed for high-boost durability. The coils incorporate reinforced thermoplastic housings, high-dielectric silicone boots, and premium magnetic core windings that resist heat soak and prevent voltage leakage. The included spark plugs feature laser-welded iridium center electrodes paired with platinum ground discs to resist thermal erosion and prevent gap expansion under boost. Matched to interchange numbers 5C2295 and UF854, this kit ensures a stable spark arc across all operating ranges.
