Ignition Coil and Iridium Spark Plugs for BMW X5 (2013-2016) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2016 BMW X5

What it Does: Replaces degraded factory ignition coils and fouled plugs to restore precise combustion timing, eliminate high-load misfires, and smooth out erratic idle on 3.0L turbo inline-six engines.

The Stock N55 Ignition Coil Breakdown

The forced-induction environment of the 3.0L N55 engine subjects cylinder-head-mounted ignition coils to intense thermal cycling and high cylinder pressures. Over time, OEM coil housings suffer from dielectric breakdown and micro-cracking in the primary/secondary copper windings, causing spark energy leakage, hesitation under boost, and rough cold starts. Standard spark plug electrodes also widen in gap rapidly due to sustained high combustion chamber temperatures, increasing electrical resistance and accelerating premature coil failure.

The Engineering Solution

This comprehensive ignition service kit features heavy-duty coil-on-plug assemblies engineered with high-conductivity copper windings, reinforced silicone boots, and heat-resistant epoxy shielding to prevent voltage leakage. Paired with fine-wire iridium spark plugs that require lower firing voltage while maintaining superior thermal stability, this package provides a dense, consistent spark arc across the entire rev range. Direct-fit blade terminals ensure plug-and-play installation without wire harness modification.
