If the ignition coil is used improperly, it will cause damage to the ignition coil, so you need to pay attention to:
Prevent ignition coil from heating or damping.
Do not turn on the ignition switch when the engine is not running.
Check, clean, and tighten line joints regularly to avoid short circuits or tie-ups.
Control Engine Performance to Prevent over-voltage.
The moisture on the ignition coil can only be wiped with a cloth, otherwise, the ignition coil will be damaged.

Q1: How long can I Drive with a Bad Ignition Coil?
A: Although most vehicles will still move with bad ignition coils, they will have a myriad of issues from misfires to hesitation. Hence, the simple answer is that you should not drive with bad ignition coil to prevent even more serious vehicle problems.
Q2:Do High Performance Coils Make a Difference?
A: Yes, they can make a difference as the increased voltage boosts vehicle power and improves fuel economy. However, the difference is not that significant when compared to regular ignition coils.
