Ignition Coil + Iridium Spark Plugs for BMW M5 (2006-2010) 5.0L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2006-2010 BMW M5

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces worn factory ignition components on the 2006-2010 BMW M5 to eliminate high-RPM misfires, stabilize uneven idle, and restore crisp throttle response across all ten cylinders.

The Stock BMW M5 Ignition Degradation

The naturally aspirated 5.0L S85B50 V10 operates at engine speeds up to 8,250 RPM, generating severe underhood heat cycles in the E60 engine bay. Over time, OEM ignition coils suffer internal dielectric insulation breakdown and thermal micro-cracking. This degradation causes secondary voltage leakage under load, triggering false ionic current misfire faults via the MSS65 DME, erratic hesitation, and unburned fuel washing down the cylinder bores. Standard spark plugs also suffer rapid center electrode wear in high-compression (12.0:1) conditions.

The Engineering Solution

This 10-cylinder ignition kit is engineered to restore factory-calibrated ignition energy. The replacement pencil coils feature high-conductivity copper primary and secondary windings encased in thermal-resistant epoxy to resist heat soak and voltage arc-over. Heavy-duty silicone boots resist oil deterioration and spark blowout. Paired with fine-wire iridium spark plugs featuring laser-welded tips and platinum ground pads, the kit requires less strike voltage while improving flame kernel propagation and maintaining fouling resistance through the entire RPM range.
