Ignition Coil and Iridium Spark Plugs for BMW M5 (2012-2016) 4.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2012-2016 BMW M5

Restores high-output ignition performance by replacing degraded coils and plugs to eliminate boost misfires and stabilize combustion.

The Stock S63 Ignition Breakdown

The hot-vee layout of the twin-turbo 4.4L engine traps extreme thermal energy directly above the cylinder heads, rapidly degrading OEM ignition coil insulation. Over time, high thermal cycling leads to internal epoxy breakdown, secondary winding shorts, and dielectric leakage. Combined with widened spark plug gaps from erosion, the degraded ignition system struggles to ignite high-density fuel mixtures under boost, triggering cylinder misfires, drivetrain malfunctions, and rough cold starts.

The Engineering Solution

This complete 8-cylinder ignition overhaul kit pairs heavy-duty coil-on-plug assemblies with high-temp fine-wire iridium spark plugs. The ignition coils feature high-purity internal copper windings and reinforced thermoplastic housings designed to withstand severe engine bay heat soak. The paired iridium plugs reduce required firing voltage and resist spark erosion, ensuring a stable flame kernel and precise arc delivery under maximum cylinder pressure.
