Moroso BBC Under Header 135 Deg Plug End HEI Dist Unsleeved Ultra Spark Plug Wire Set - Black

Starting with 8mm diameter wire, these Moroso Ultra Spark Plug Wire Sets are built for serious performance. The wire itself uses a high-resistance core with a fiberglass braid and a silicone jacket, all designed to handle the heat and electrical demands of a BBC engine, especially when tucked under headers. The 135-degree plug end makes routing easier around tight exhaust manifolds, and the HEI distributor end is unsleeved for a direct connection. This set comes in a clean black finish, keeping your engine bay looking sharp while ensuring reliable spark delivery.

Moroso uses a special conductive core that helps suppress radio frequency interference, which can clean up your engine's electrical noise. The silicone boots on both ends are designed to seal tightly against moisture and vibration, keeping your spark where it needs to be. These wires are a solid choice for BBC applications where space is tight and performance is key.
