How Do You Test COP Ignition Coils?

COP ignition coils, are different from spark plugs which are wear items, usually last longer than spark plugs. But lifetime is difficult to describe accurately because it is related to road conditions and driving conditions. If the road is bumpy, dusty or muddy, bad weather and bad driving habits, all these will affect the life of the COP ignition coils. According to the country’s laws, cop coil in new cars are warranted for at least two years or 22,000 miles, whichever comes first because of the insulation in COP ignition coils degrades over time. But our coil on plug ignition are designed to last 80,000 miles or more.
