Ignition Coil + Spark Plugs for Mercedes Benz M-Class (2002-2007) 5.0L

OEM-Grade Complete Ignition Coil and Spark Plug Kit for 2002-2007 Mercedes Benz M-Class (W163 / W164)

What it Does: The ignition coil and spark plug kit replaces deteriorated factory ignition hardware on the 2002-2007 M-Class to eliminate secondary voltage leaks, resolve misfires, and restore balanced combustion across all 16 spark points.

The Stock Mercedes Benz M-Class Secondary Ignition Breakdown

The 5.0L 24-valve M113 V8 engine utilizes a twin-spark cylinder head configuration where each ignition coil must power two individual spark plugs. Over sustained mileage, extreme heat soak in the cramped W163 and W164 engine compartments breaks down the internal potting compound and epoxy casings of the original 0001587803 and 0001587303 coil packs. This thermal stress causes micro-cracking and insulation breakdown, allowing high-voltage secondary current to arc to ground rather than jumping the plug gaps. Simultaneously, aged factory plugs develop worn electrode gaps that place excessive load on the primary winding circuits, generating P0300 through P0308 diagnostic trouble codes, rough cold-start idling, and catalytic converter-damaging raw fuel dump under load.

The Engineering Solution

This direct-fit overhaul kit supplies eight dual-output ignition coils paired with sixteen Denso PK16TT Platinum TT spark plugs to restore precise ignition dwell and spark energy. The ignition coils are constructed with high-dielectric thermoplastic housings and copper primary/secondary windings to prevent thermal arc-through and internal shorting. The Denso twin-tip spark plugs utilize a durable platinum center electrode paired with a titanium-enhanced ground electrode, effectively lowering the required firing voltage while maintaining superior flame kernel propagation. Installing the full set restores balanced resistance across the M113 dual-spark ignition harness, stabilizing idle harmonics and returning peak thermal efficiency.
