Ignition Coil and Iridium Spark Plugs for BMW 7 Series (2011-2015) 3.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2011-2015 BMW 7 Series

Direct-fit ignition overhaul kit: Restores factory secondary ignition voltage and combustion efficiency across all six cylinders to eliminate high-boost misfires and erratic idle.

The Stock 7 Series Thermal Degradation

The turbocharged inline-6 in the F01/F02 chassis generates extreme underhood thermal loads. Over extended heat cycles, factory coil epoxy insulation breaks down, causing secondary voltage leakage and internal winding resistance drift. Combined with premature electrode erosion on standard plugs under boost, this degradation triggers DME misfire fault codes, hesitation during tip-in, and rough idle.

The Engineering Solution

This matched 6-cylinder ignition service kit features direct-replacement coil-on-plug assemblies engineered with high-conductivity internal copper windings and reinforced dielectric thermoplastic housings. Paired with high-temperature iridium-tipped spark plugs, the kit maintains optimal gap stability and a concentrated spark kernel under cylinder pressure, ensuring clean combustion and restored throttle response.
