Mantis High-Output Ignition Coil — BMW / MINI / Toyota Supra B-Series Performance Ignition Coil (B38 / B48 / B58 / S58)

Built for BMW's B-Series turbocharged engines — B38, B48, B58 and S58 — found across the BMW, MINI and Toyota GR Supra range, this Mantis high-output ignition coil is the direct upgrade for drivers chasing a stronger, more consistent spark under boost. Whether your B58 is running factory power or a Stage 2 remap, weak OE coils are often the first ignition component to struggle as cylinder pressure climbs.

Why Choose the Mantis MTP-1006?

• 12% More Spark Energy — a neodymium (NdFeB) magnetic core reaches saturation faster than the standard ferrite OE coil, storing more energy for a hotter, more powerful spark.
• Built for Boost — secondary current of up to 2x standard output keeps the B38/B48/B58/S58 firing cleanly under load, helping prevent the ECU pulling timing to guard against misfire.
• Bigger Flame Kernel — more of the air-fuel mixture ignites in the first milliseconds of combustion, for a smoother idle, sharper throttle response and cleaner emissions.
• True Plug & Play — a direct OE replacement for BMW, MINI and Toyota Supra B-Series applications. No wiring changes, no coding, no ECU remapping required.
• 2-Year Warranty, UK Stock — UK-engineered and tested, with orders placed before 3pm dispatched the same day.

Rough idle, hesitation under load, a flashing check engine light or misfire codes (P0300–P0308) on your B-Series BMW, MINI or Supra? Fit the Mantis MTP-1006 and restore the strong, reliable spark your engine was designed for.
