Moroso BBC Over Valve Cover Str Plug Boots HEI Sleeved Ultra Spark Plug Wire Set - Red

These Moroso spark plug wire sets are built for big-block Chevrolet (BBC) engines using HEI distributors. The wires feature a silicone jacket over a fiberglass braid, with a suppression core to cut down on radio frequency interference. This helps ensure a clean spark signal to your plugs, which is important for consistent engine performance. The straight plug boots fit over the valve covers, giving you a tidy look and making installation easier on many BBC applications.

Moroso uses a special boot construction that's designed to handle the heat generated by the engine. The HEI sleeves are there to protect the wires where they pass near the distributor cap, preventing potential damage and ensuring a reliable connection. This set comes in red, offering a pop of color under the hood for those who like to dress up their engine bay.
