BMW M140i & M240i (B58) Performance Ignition Coils - Mantis MTP-1006

Built for BMW's B58 3.0 turbo straight-six in the M140i, M240i, M340i, M440i and Z4 M40i, this Mantis high-output ignition coil is the direct upgrade for one of the best-value performance engines of the decade — a simple map adds 100PS or more, which is why almost every one of these cars ends up tuned and why their six coils live a hard life.

Why Choose the Mantis MTP-1006?

• 12% More Spark Energy — a neodymium magnetic core stores more energy than the standard ferrite OE coil, for a stronger spark on all six cylinders.
• Built for Boost — tuned B58s are known for boost misfires as standard coils age; the MTP-1006 holds its output pull after pull on Stage 1 and Stage 2 cars.
• Bigger Flame Kernel — more complete combustion for smoother running and no flat spots on boost.
• Direct OE Plug & Play — fits every B58 car including the 540i, X3/X4 M40i and Z4 M40i. No wiring or coding changes.
• 2-Year Warranty, UK Stock — UK-engineered with every unit tested, same-day dispatch on orders before 3pm.

Seeing P0301–P0306 or drivetrain errors on ISTA or Bimmerlink? Fit a full set of six Mantis MTP-1006 coils in around 30–40 minutes — mixed-age coils cause uneven spark across the bank and the ECU pulls timing to compensate.

Let's check it fits

The Mantis MTP-1006 is compatible with the following cars fitted with the BMW B58 3.0 turbo engine — 6 coils per car. It's always a good idea to verify your existing coil's OE number too (listed below).
