Frequently Asked Questions

Will these work with my stock Harley ECU?

Yes. ION Sense feedback ensures full compatibility with stock Harley EFI systems without modifications or a separate tuner.

How much hotter is the spark compared to stock coils?

Peak spark voltage increases by 20% or more, which improves ignition under all conditions, especially in cold starts and at high RPM.

Do I need to replace both coils or just one?

You can replace one or both. Many riders upgrade both for consistent ignition across all cylinders.

Will this fix my misfires at highway speeds?

High-speed misfires are often caused by weak spark at high RPM. These 30,000-volt coils eliminate that issue in most cases.

Is installation difficult?

Coils are bolt-on replacements for stock units. No special tools or tuning required — basic socket set is all you need.
