Ignition Coil & Iridium Spark Plugs for BMW 320i xDrive (2013-2018) 2.0L

High-Output Ignition Coil & Iridium Spark Plugs for 2013-2018 BMW 3 Series (N20/B48 / F30)

Direct-Replacement Ignition Service Kit: This comprehensive pack of four ignition coils and iridium laser spark plugs restores optimal spark energy and corrects common misfire conditions in the 2.0L turbocharged BMW 3 Series.

The Stock 3 Series Ignition Weakness

The factory BMW ignition system on the N20 and B48 2.0L engines is notoriously prone to premature coil degradation and spark blowout under high load. Heat soak from the compact, turbocharged engine bay combined with high operating voltages often causes the internal epoxy to break down, leading to micro-cracks in the coil housings. When the OEM spark plug electrodes wear down over time, the increased gap demands higher firing voltage, pushing aging stock coils past their thermal limits. This cascade effect inevitably results in rough idling, hesitation during acceleration, decreased fuel economy, and persistent cylinder misfire trouble codes under heavy boost.

The Engineering Solution

This replacement ignition coil and iridium spark plug package is engineered to exceed factory tolerances and deliver a much stronger, more consistent spark arc. The upgraded coils utilize high-grade copper windings and premium silicone boot construction, significantly reducing internal resistance and preventing high-voltage leaks to the cylinder head. Combined with the laser-welded iridium spark plugs, which feature an ultra-fine center electrode for superior ignitability, this system requires less voltage to generate a spark while maintaining stability under high cylinder pressures. By ensuring a complete and efficient fuel burn, this kit maximizes thermal efficiency, restoring lost horsepower and torque, smoothing out the idle, and protecting your catalytic converter from unburned fuel exposure.
