FM40 Ignition Coil

Gill Instruments FM40 coils are a low cost solution for smaller spark ignited engines and are particularly suited for normally aspirated, stoichiometric fuelled gas engines up to approximately 1.5 litres (90 cubic inches) per cylinder.

They are designed to function with Gill Instruments inductive igniters providing the long programmable spark duration required for clean burning internal combustion engines.
