Product Description
Michigan Motorsports 4" Black Spark Plug Wire Protectors – Set of 8
High-Temperature Heat Shield Sleeves for LS & LT Engines with Valve Cover–Mounted Coils
Michigan Motorsports 4" Black Spark Plug Wire Protectors are engineered to protect your ignition system from extreme exhaust heat commonly found in LS and LT engine bays. Constructed from durable dual-layer woven fiberglass, these high-temperature sleeves shield spark plug wires from burning, chafing, and heat soak—helping extend wire life and maintain consistent ignition performance. The shorter 4" length, compared to traditional 6" protectors, is ideal for LS and LT engines with valve cover–mounted coils, providing targeted protection without excess bulk. Finished in a stealthy black color, these sleeves deliver both performance protection and a clean, understated look.
