What is a suppression core wire?

A suppression core wire contains a resistive element within the conductor. This design helps to absorb and dissipate electrical energy that can cause radio frequency interference (RFI), which can sometimes affect electronic components on your motorcycle.

What does the black silicone jacket do?

The black silicone jacket on these wires serves to protect the internal conductor from heat generated by the engine and from abrasion. This helps to ensure the longevity and reliable performance of the spark plug wires.

Are these wires difficult to install?

These wires are designed as a direct replacement for your stock ignition wires. While installation is generally straightforward, it's always a good idea to refer to your Harley-Davidson's service manual for specific procedures and torque specifications.
