Cable Master: High Performance Spark Plug Wire Set for HEI SBC BBC 5.0L-5.7L V8 (1987-1996)

Upgrade your GM small-block V8 with Cable Master’s High Performance Spark Plug Wire Set

Designed for 1987–1996 HEI-equipped GM engines, this Cable Master wire set blends rugged construction with precise electrical delivery. It’s built to accompany classic SUVs and trucks through demanding driving scenarios, helping your ignition system maintain steady spark delivery and reduce energy loss under heat and vibration.

Durability engineered for the long haul

• Kevlar core for maximum durability and long life
• Durable nickel wire wound conductor to support engine performance
• Low resistance, high-energy MAG conductor for efficient voltage delivery

Insulation and protection for harsh environments

• High-tear strength double silicone jacket with a fiberglass wire layer
• Heat-resistant insulation maintains a stable electric connection in hot environments

Premium silicone jackets and boots add another layer of protection, helping resist heat and vibration while maintaining a reliable seal around each boot. This combination supports consistent spark delivery and reduces the risk of energy loss in challenging conditions.

EMI suppression and electronics compatibility

• Superior RFI suppression for sensitive electronic systems
• Low-resistance wiring helps minimize voltage drop across the spark plug wires

The result is a cleaner signal path through the ignition system. While improvements depend on the vehicle’s condition and installation quality, these wires are designed to help maintain steady electrical performance across a range of applications.

Fitment and applications

This set targets GM platforms including Hummer Blazer, Suburban, and W-series Yukon families, covering 5.0L and 5.7L V8 engines from 1987 onward. It aligns with SBC and BBC configurations commonly found in classic trucks and SUVs, offering a straightforward upgrade path for enthusiasts who value durability and reliable spark delivery.
