Audi Ignition Coil - Hitachi 8A0905105

Product Information

Direct ignition coils are located directly over the top of the spark plug. In this ignition setup there is one ignition coil per spark plug and there are no spark plug wires. This ignition setup is often referred to as a coil on plug ignition system.

Coil on plug or direct ignition systems are pretty much used on all modern cars due to packaging, performance, emissions, and maintenance reasons. This ignition system is essentially maintenance free with the exception of spark plug replacements and the occasional coil replacement when compared to a traditional ignition system.
