Signs of a Bad Ignition Coil
How long do engine coils last?
Average lifetime of ignition coil is around 100,000 miles or more. It is not an easy worn out replacement car part but still could fail for variety of reasons. via
Do coil packs improve performance?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase. via
Are coil packs the same as spark plug wires?
Coils packs are individual coils that 'power' the sparks plugs and sit directly on top of the plugs, spark wires are high tension or voltage wires which carry the current from a shared coil which may power all cylinders. Coil pack is an individual coil that sits directly on top of the spark plug . . . via
