Mantis High-Output Ignition Coil — BMW N54 / N55 / S55 Inline-6 Performance Ignition Coil (M3 F80, M4 F82, M2 Competition, M235i, M140i, 335i, 435i)

Purpose-built for BMW's iconic N54, N55 and S55 turbocharged inline-six engines, this Mantis high-output ignition coil is the direct replacement for the M3 (F80), M4 (F82), M2 Competition, M235i, M140i, 335i and 435i. These engines are popular remap and big-turbo platforms, and factory coils are frequently the weak link once boost and cylinder pressure climb beyond standard.

Why Choose the Mantis MTP-1007?

• 12% More Spark Energy — the neodymium magnetic core saturates faster than a standard ferrite coil, storing more energy for a stronger, hotter spark at the plug.
• Reliable Firing Under Boost — with up to double the secondary current of an OE coil, the MTP-1007 is engineered to keep firing cleanly on tuned N54/N55/S55 applications, reducing the risk of misfire and timing retard.
• Smoother, More Complete Combustion — a larger initial flame kernel burns more of the air-fuel charge early in the cycle, for a smoother idle and cleaner exhaust.
• Direct OE Plug & Play — fits straight in place of the original coil on M3, M4, M2 Competition, M235i, M140i, 335i and 435i models. No adapters, no coding.
• 2-Year Warranty, Same-Day UK Dispatch — UK-engineered and stocked, with orders before 3pm shipped that day.

Rough idle, hesitation off boost, or a misfire code on your N54, N55 or S55? Upgrade to the Mantis MTP-1007 and give your BMW inline-six the ignition strength it needs — stock or tuned.

Let's check it fits

The Mantis MTP-1007 is compatible with the following cars fitted with the BMW N54 / N55 / S55 inline-6 (M3 F80, M4 F82, M2 Comp, 335i, 435i, M235i, M140i) engines, plus the shared PSA/Volvo pencil-coil family. It's always a good idea to verify your existing coil's OE number too (listed below).
