Moroso BBC Under Header 135 Plug Boots HEI Ultra Spark Plug Wire Set - Red

Moroso is known for making well-built performance parts for racing and street applications. This spark plug wire set is designed for BBC (Big Block Chevy) engines using an HEI distributor and routing spark plug wires under the exhaust headers. The wires come in a vibrant red color, adding a clean look to your engine bay.

Each wire features a 135-degree boot on the spark plug end. This specific angle is crucial for clearing exhaust headers, especially when the wires need to run underneath them. This design helps prevent the wires from touching hot exhaust components, which can cause damage and misfires. The set includes everything needed to replace your old wires, ensuring a straightforward installation for your Big Block Chevy.
