8.5MM Wire Set - 68-Up AMC V8

The MSD IGNITION 8.5MM Wire Set is a complete spark plug wire assembly engineered for 1968 and later AMC V8 engines. This spiral-core conductor system replaces aging or damaged factory wiring on classic American muscle cars and street machines, restoring reliable spark delivery to all eight cylinders. Designed for enthusiasts and professional builders who demand consistent ignition performance without the complexity of expensive ignition system overhauls, this wire set delivers proven reliability at a fraction of full-system replacement costs.

Each wire features an 8.5-millimeter super conductor core that suppresses electromagnetic interference while maintaining excellent spark plug firing efficiency under load. The spiral-wound design minimizes radiated noise and prevents cross-fire between adjacent cylinders—critical on high-output V8s running near compression limits. Black insulation jacket withstands underhood heat cycling, oil spray, and vibration without degradation. Straight plug boots and socket-style connections ensure secure seating on original or aftermarket spark plugs, eliminating loose connections that cause misfires and rough idle conditions.

This wire set suits restorers, hot rodders, and daily-driver owners keeping classic AMC V8 engines on the road. Installation requires no special tools—simply disconnect old wires one at a time and route new conductors along original harness paths to prevent heat damage or accidental contact with headers and exhaust manifolds. Compatible with all 1968-and-up AMC V8 engines including Rambler, Javelin, AMX, and Gremlin models equipped with standard V8 powerplants. MSD's reputation for quality ignition components ensures longevity and trouble-free performance through thousands of miles.
