Moroso BBC Under Header 90 Deg Plug HEI Dist. Unsleeved Ultra Spark Plug Wire Set - Black

Moroso is known for making performance parts for racing and street applications. This particular spark plug wire set is built for big block Chevrolet engines using an HEI distributor and routing the wires under the exhaust headers. The unsleeved design helps keep the wires flexible and easy to route, especially in tight engine bays where you need to tuck them away from the heat of the headers.

These wires use a 90-degree boot on the spark plug end, which is common for HEI distributors and helps ensure a solid connection. The unsleeved construction means they are more pliable than sleeved wires, making installation simpler when you're trying to snake them around exhaust components. This set is designed to fit right and provide a reliable connection for your ignition system.
