Racing Power Company (R4607): High-Performance V8 Spark Plug Wire Set (8mm, 90°)

The High-Performance 8mm Spark Plug Wire Set delivers exceptional performance at an unbelievably affordable price. This set is designed to deliver greater spark energy while improving power, idle, and fuel efficiency. It also works in conjunction with most ignition systems, on-board computers, and electronic components.

This Spark Plug Wire Set features a helically Spiro-wound core conductor with a 500 Ω/ft resistance that suppresses Electro Magnetic Interference (EMI) and Radio Frequency Interference (RFI). The core conductor is made with Dupont™ Kevlar® aramid fiber. Each wire is wrapped in a durable, synthetic-silicone, double-layer jacketing that resists heat, oil, and abrasion. This set also includes pre-installed, 90° black silicone boots to protect against high exhaust temperatures up to 600°F. The double-locking spring terminals provide secure, vibration-proof connections.
