These HT leads feature a solid copper core for maximum conductivity and consistent performance.
Copper core ignition leads are known for their exceptional electrical conductivity, providing a strong and reliable spark across all engine speeds. This makes them particularly well-suited for classic vehicles and engines that rely on traditional ignition systems.

The leads are encased in high-grade silicone insulation, offering excellent resistance to heat, oil, moisture, and chemical exposure. This ensures long-term durability, even under the harsh conditions of engine bays.

While copper core leads do not have built-in suppression, they are often preferred in applications where electromagnetic interference (EMI) is not a concern, or where external suppression (such as in the distributor cap or spark plugs) is already provided.

These leads are ideal for vintage and performance vehicles where authenticity, low resistance, and spark strength are key priorities.
