Ignition Coil and Iridium Spark Plugs for BMW X3 (2013-2016) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2016 BMW X3

Primary Function: Restores complete combustion efficiency and eliminates cylinder misfires on the turbocharged 3.0L inline-six engine by replacing worn secondary ignition components.

The Stock F25 Thermal Degradation Weakness

The BMW N55 engine operates under high thermal loads and elevated cylinder pressures due to forced induction. Over time, the factory coil-on-plug boots suffer from dielectric breakdown, thermal cycling fatigue, and internal resistance drift. This causes micro-arcing, intermittent under-load misfires (DTC 2EFE/2EFF series), rough idle speeds, and unburnt fuel entering the catalytic converter.

The Precision Engineering Solution

This comprehensive service kit includes six high-dielectric coil packs and matched fine-wire iridium spark plugs. The ignition coils feature premium-grade internal copper windings and reinforced thermoplastic housings to resist engine bay heat soak. Matched with high-durability iridium electrodes that maintain a precise gap under peak boost, this setup guarantees stable spark energy, crisp throttle response, and complete flame propagation across all six cylinders.
