Product Description
Michigan Motorsports 4" Silver Spark Plug Wire Protectors – Set of 8
High-Temperature Heat Shield Sleeves for LS & LT Engines with Valve Cover–Mounted Coils
Michigan Motorsports 4" Silver Spark Plug Wire Protectors are designed to shield your ignition wires from extreme exhaust heat commonly found in LS and LT engine bays. Constructed from durable dual-layer woven fiberglass, these high-temperature sleeves protect spark plug wires from burning, chafing, and heat soak—significantly extending wire life and ignition reliability. The shorter 4" length is ideal for LS/LT engines with valve cover–mounted coils, where traditional 6" sleeves can be unnecessary or cumbersome. Finished in a clean silver color, these protectors add both performance protection and a polished look to your engine bay.
