What is the main benefit of upgrading ignition wires?

Upgrading your ignition wires helps ensure a strong and consistent spark to your spark plugs. This can lead to improved engine performance and efficiency, especially if your old wires are degraded.

Are these wires difficult to install?

These ignition wires are designed as a direct replacement for your factory set. Installation typically involves unplugging the old wires and connecting the new ones in the correct order.

What does the high-resistance core do?

The high-resistance core in these wires helps to suppress radio frequency interference (RFI). This can lead to a cleaner electrical signal in your engine bay and potentially reduce static on your radio.
