| + | ^ Coil Switching | Mechanical separation of contacts | Transistor | | ||
| + | ^ Coil Pulse | Slow | Sharp | | ||

| + | ^ Wear and Tear Items | Contact-breaker point\\ Contact-breaker spring\\ Condenser\\ Distributor cap and rotor contacts | None (not user serviceable) | | ||
| + | ^ Failure Mode | Gradual (knocking, loss of performance) | Sudden (electronic failure) | | ||
| + | |||
| + | Overall, an electronic distributor provides more consistent ignition, which results in a more efficient engine; it also provides optimum timing and higher performance throughout its service life with zero maintenance. | ||
| + | |||
| + | However, it comes with the tradeoff that any failure of electronics will be sudden, without developing early warning symptoms, and a failed electronic distributor can generally only be repaired with a 1:1 swap. | ||

| + | * If you had purchased a pack of 4, it is expected to have one left over, safekeep it as a spare | ||
| + | * Inspect the original spark plugs, if they are in good condition (no structural damage, excessive wear or heavy deposits), keep them as a spare together with the contact point distributor | ||
