Ignition Coil & Iridium Spark Plugs for BMW 328i xDrive (2013-2016) 2.0L

High-Output Ignition Coils & Iridium Spark Plugs for 2013-2016 BMW 3 Series (N20 / F30)

Designed for high-compression turbocharged applications: This direct-replacement ignition coil and iridium spark plug kit restores spark efficiency, eliminating misfires and supporting optimal combustion in the N20 powertrain.

The Stock 3 Series Ignition Shortfall

The factory ignition coils on the BMW N20 powertrain are notoriously prone to premature degradation, especially under sustained thermal load and elevated boost pressures. Heat soak from the turbocharged 2.0L block significantly increases electrical resistance within the OEM coil windings. Over time, this thermal cycling breaks down the internal epoxy insulation, leading to voltage leaks, inconsistent dwell times, rough idling, and inevitable cylinder misfires under heavy load. Combined with standard worn spark plugs experiencing gap erosion, the N20 engine suffers from incomplete fuel burns, reducing torque output and causing erratic drivability.

The Engineering Solution

This upgraded ignition kit resolves these factory deficiencies by utilizing high-dielectric epoxy and reinforced copper windings inside the ignition coils, maximizing voltage output to the plugs while resisting breakdown from engine bay heat soak. The inclusion of iridium laser performance spark plugs ensures a precise, concentrated spark kernel. Iridium's exceptional melting point and structural rigidity prevent premature gap expansion, allowing for a highly efficient fuel burn across all RPM ranges. The direct-fit blade terminals ensure seamless integration with the factory wiring harness, providing a stable, high-voltage spark that stabilizes idle, restores lost efficiency, and ensures reliable torque delivery.
