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.
This valve spring kit, designed for performance built engines, is a critical component for those demanding peak performance from their vehicles. The kit includes a set of 16 springs that mount to the stock OEM retainers.
Upgrade your engine's performance with this high-quality valve spring kit, ensuring optimum power and reliability.

Enhance the performance of your Mini with Supertech Pistons, crafted from extruded high silicone, enhanced 4032 alloy for superior durability and thermal conductivity. Withstanding up to 42psi of boost, these pistons feature a fine structural grain achieved through a two or three step forging process and precise CNC machining. Heat treatments ensure high tensile strength and hardness, while contact reduction grooves and honed pin bores provide a precise fit. Wrist pins made of cold extruded chrome moly steel offer exceptional strength. Plus, a 'phosphate dry lubricant' coating protects rings from 'micro-welding' and enhances lubrication on the skirt/cylinder area. Compression ratios are computed with .030" head gasket and .010" deck, offering optimal performance for your Mini.
