Ignition Coil and Iridium Spark Plugs for BMW 3 Series (1996-2002) 2.5L 2.8L

Direct-Fit High-Conductivity Ignition Coil and Iridium Spark Plug Kit for 1996-2002 BMW 3 Series

Restores lost combustion efficiency and eliminates multi-cylinder misfires: This direct-replacement ignition service kit provides six precision-wound coil-on-plug units and matched fine-wire iridium spark plugs for BMW M52 and M54 inline-six engines.

The Stock 3 Series Ignition Coil Degradation

Under-hood thermal cycling on the inline-six chassis severely degrades factory coil insulation and epoxy encapsulation over time. As the internal windings break down from sustained high-temperature exposure, secondary resistance climbs, resulting in dielectric puncture, weak arc energy, erratic idle, and partial-throttle hesitation under load.

The Engineering Solution

Engineered with high-grade electrolytic copper primary and secondary windings, these replacement coils deliver stable high-voltage output across all engine speeds. Matched with corrosion-resistant iridium spark plugs featuring ultra-fine center electrodes, this kit reduces required firing voltage, accelerates flame-kernel expansion, and prevents electrical leakage under high cylinder pressures.
