The MINI N14 engine uses a traditional pencil coil design that operates using conservative dwell times and relatively low discharge energy. On stock vehicles, this system is sufficient. However, as cylinder pressures increase via higher boost, upgraded turbos, or ethanol-blended fuels, the strength required to bridge the spark gap increases substantially.
Under these conditions, standard N14 coils reach their electrical limits, resulting in high-RPM spark blowout, misfires, or reduced flame front propagation. To solve this issue, our team engineered the B-Series Coil Conversion Kit, which adapts modern BMW B48/B58 ignition technology to the N14 using proprietary brackets, standoffs, and wiring harness adapters. Our performance B48 ignition coils feature a significantly lower primary resistance and an optimized secondary winding structure, allowing them to store and release up to 2.3x more spark energy than the factory N14 ignition coil.
This clean, coil-on-plug upgrade drops directly into your valve cover without bulky external boxes or messy wiring. Whether you need an ignition service or are building a tuned N14, upgrade to B-Series ignition coils and experience improved spark energy and long-lasting performance.
