About the Mantis MTP-1023 BMW V8 Performance Ignition Coils.
Eight coils for the hot-vee S63/N63 - the hardest-worked ignition in BMW's range.
The 4.4 twin-turbo V8 mounts its turbos inside the vee, which cooks everything around them - coils first. M5 F10s, M6s and 50i-badged cars are notorious for sequential coil failures from 50k miles, and tuned examples eat them faster still.
The Mantis MTP-1023 is a direct replacement engineered around a neodymium core delivering 12% more spark energy than standard OE coils - with the thermal headroom this engine bay demands. Fit eight, forget them.
Signs your V8 needs new coils
> Single-cylinder misfires, often rotating between cylinders
> Rough idle, shuddering under load
> Drivetrain malfunction warnings
> P030x codes
> Coils original past 50k miles
