MSD 5565 Street-Fire Spark Plug Wire Set Small Block Chevy Socket Cap Over Valve Cover

The MSD 5565 Street-Fire Spark Plug Wire Set is a pre-terminated, ready-to-install ignition wire set engineered specifically for Small Block Chevrolet engines equipped with an early socket-style (non-HEI) distributor cap, with wires routed over the valve covers. This set delivers genuine MSD ignition performance at an accessible price point, making it an ideal upgrade for street-driven SBC-powered vehicles.

At the core of each wire is a helically wound spiral conductor that provides 500 ohms per foot of resistance for optimized spark delivery while effectively suppressing electromagnetic interference (EMI) and radio frequency interference (RFI). The 8mm black sleeve combines silicone and synthetic jacket materials to resist engine heat and abrasion, while a Kevlar/Aramid core reinforces each wire for long-term strength and durability.

Key Features:

• 8mm diameter black wire with silicone and synthetic jacket for heat and abrasion resistance
• Helically wound spiral core conductor — 500 ohms/ft resistance for improved spark delivery and power
• Kevlar/Aramid core for superior strength and durability
• Silicone boots on all terminals to protect against high exhaust temperatures
• Heavy-duty terminals for secure, reliable connection

Important Notes: This set is designed for use with early socket-style distributor caps on Small Block Chevrolet engines. It is not compatible with stock GM or aftermarket cast-housing distributors, and requires modification if used with an MSD Street Fire distributor. Wires are routed over the valve covers. Legal for use on emissions-controlled, non-emissions-controlled, and race-only vehicles.
