ignition coils

Engine spark makers

Ignition coils are electromagnetic devices in internal combustion engines that transform battery voltage into the high voltage needed to create a spark at the spark plugs.

Each cylinder typically has its own coil in modern engines: The mechanic said two ignition coils needed replacing.

When coils fail, engines misfire or run rough.
