Dinan B-Series performance ignition coil (red), a direct plug-and-play upgrade over the factory coil delivering up to 10% more spark energy for stronger, more consistent combustion - useful both for stock reliability and for supporting a tuned engine's higher cylinder pressures.

Fitment: BMW/MINI/Toyota B-series engine models - B38, B46, B48, B58 and S58 across F/G-series BMW, MINI Cooper/JCW, and the A90 Supra (confirm exact engine at checkout; sold individually - a matched set of 4 or 6 is recommended for a full engine).
