Designed for the professional technician and meet or exceed OEM manufacturers specifications
The primary winding of the ignition coil is wound with a small number of turns and has a small resistance, applying the battery to this coil causes a sizable DC current to flow
Manufactured to meet or exceed OEM standards and specifications
Modern coil designs produce voltage pulses up in the neighborhood of 40,000 volts from the interruption of the 12-volt power supplied by the battery
Some modern engines have multiple ignition coils mounted directly on the sparkplugs and instead of single voltage pulses, they may under some engine conditions produce three voltage pulses

What does an ignition coil do?

An ignition coil transforms low battery voltage into the high voltage needed to create a spark in the spark plugs.

What are the different types of coils?

Common types include single coil with distributor, coil packs, coil-on-plug (COP), and wasted spark systems.

How long should an ignition coil last?

Most ignition coils last between 80,000 and 100,000 miles under normal conditions.
Power Meets Precision.
Signs of a failing ignition coil?

Misfires, rough idle, check engine light, poor fuel economy, and hard starting are typical signs of coil failure.

Why do ignition coils fail?

They fail due to heat, vibration, moisture, bad spark plugs, or electrical overload.

Can you drive with a bad ignition coil?

You can, but it’s unsafe and can damage other components like the catalytic converter.
Engineered for Performance.
How do you diagnose a faulty ignition coil?

Use an OBD-II scanner, swap coils, inspect visually, and check resistance with a multimeter.

Can you repair an ignition coil?

Ignition coils are not repairable and should be replaced when faulty.

How to extend ignition coil life?

Regular spark plug maintenance, keeping connections clean, and preventing oil leaks help extend coil life.
