MSD 5569 Street-Fire Spark Plug Wire Set Big Block Chevy 454 1988-Up

The MSD Street-Fire 5569 is a direct-fit spark plug wire set engineered for Big Block Chevy 454 engines with factory HEI ignition from 1988 and up. Designed as a performance upgrade over stock wiring, these Street-Fire wires deliver reliable, low-resistance spark transfer in a durable, heat-resistant package at an exceptional value.

Each wire features a helically wound spiral-core conductor that effectively suppresses electromagnetic interference (EMI) and radio frequency interference (RFI), keeping your ignition signal clean and your electronics interference-free. The conductor is reinforced with a Kevlar core for added tensile strength and long-term durability. A low-resistance design ensures maximum energy reaches the spark plug for a complete, efficient combustion event.

• 8mm silicone/synthetic jacket resists heat, abrasion, and common automotive chemicals and fluids
• Helically wound conductor suppresses EMI/RFI for clean ignition signal
• Kevlar-reinforced core for superior strength and durability
