Why does the same ignition coil keeps failing?

Why does the same ignition coil keeps failing?

The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.

Are ignition coils sold separately?

Pencil ignition coils and blocks are sold individually and in sets, so if you’re after a coil pack, specify it by selecting the specific type in the design category.

What is a good aftermarket ignition coil?

What happens if ignition coil goes bad?

One of the most common symptoms associated with a faulty ignition coil is engine performance issues. Faulty coils may cause the vehicle to experience misfires, a rough idle, a loss in power and acceleration, and a reduction in gas mileage. In some cases the performance issues may even result in the vehicle stalling.

How do you stop ignition coils from failing?

Keeping your spark plugs in optimum condition can reduce your chances of experiencing an ignition coil failure. As spark plugs wear down, the gap in which each spark plug is fired is widened, meaning the coil needs to provide a higher voltage in order to bridge the gap.

Can I use aftermarket ignition coil?

Aftermarket ignition coils are never worth the extra few bucks in savings. In a few cases, you can get away with using a cheap universal aftermarket part as long as it doesn’t affect: The engine’s performance. The vehicle’s safety.

Do performance ignition coils add horsepower?

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.

Will new ignition coils improve performance?

Engine performance can be helped by a high performance ignition coil. The higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal. The result is an increase in engine power.
