Constructed with black high-temp silicone insulation that withstands over 500°F without performance drop—ideal for high-heat conditions and performance applications.

EMI/RFI Suppressing Spiral-Wound Stainless Core

Effectively blocks unwanted electromagnetic and radio interference, preserving consistent signal flow to support today’s advanced ECUs and aftermarket ignition control systems.

American-Made Quality You Can Rely On
