Cable Master 10.2mm Racing Spark Plug Wires for GM V8 — Blue, Kevlar/Nickel Core

Cable Master 10.2 mm racing spark plug wires are a high-performance replacement set engineered for GM LS-family V8 engines, delivering durable insulation, low resistance, and improved ignition reliability in a striking blue finish.

These wires are designed to fit a broad range of Chevrolet and GMC V8 models from 2008 through 2020 (and compatible later years), including Escalade, Silverado, Suburban, Tahoe, Camaro, Corvette, Yukon and many vans and trucks using small-block Gen III/IV (LS-based) engines. Built with a Kevlar-reinforced core, nickel wire-wound conductor and double silicone jacketing, the set balances longevity, heat tolerance and strong electrical performance for street and light performance use.

Which vehicles and engines will these wires fit?

These spark plug wires are made for GM small-block Gen III/IV V8 engines with displacements commonly listed as 4.8L, 5.3L, 6.0L, 6.2L and 7.0L. They cover a long list of models from 2008 through 2020 and fit many OEM part references for direct replacement.

• Covers Escalade, Avalanche, Camaro, Colorado, Corvette, Express vans, Impala, Silverado, Suburban, Tahoe, Canyon, Savana, Sierra, Yukon and more.
• Compatible with 4.8L/294, 5.3L/325, 6.0L/364, 6.2L/376 and 7.0L/427 V8 LS-family engines.
• Designed to match common OEM part numbers and direct-fit routing for 2008–2020 model years.

How do these wires improve ignition performance?

The combination of a nickel wire-wound conductor and a Kevlar core produces low electrical resistance and reliable voltage delivery to spark plugs. That supports stronger, more consistent spark energy under load, especially at higher RPMs.

• Low-resistance mag-style conductor for efficient voltage transfer.
• Kevlar core for tensile strength and longer life under vibration.
• Premium silicone jacketing to retain performance at elevated under-hood temperatures.

Are these wires durable and heat-resistant?

Yes — the construction focuses on heat and abrasion resistance. A double-layer silicone jacket with a fiberglass wire layer provides tear resistance and insulation, while high-temperature boots protect critical connection points.

• High-tear-strength double silicone outer jacket prevents cracking and wear.
• Fiberglass reinforcement layer adds mechanical protection around the conductor.
• Heat-resistant boots and silicone keep electrical connections stable near hot exhaust components.

What installation and fit details should I know before buying?

The set is packaged for direct replacement on compatible GM applications and follows OEM-style lengths and terminal types for straightforward installation. Basic mechanical skill and common hand tools are typically all that’s required to swap the wires.

• Sold as a complete kit with required lengths for V8 firing order routing.
• Boots and terminals are shaped for OEM-style spark plug and coil connections.
• Ideal for DIY replacement during tune-ups or when upgrading stock wires for performance use.

Who is this for: This Cable Master wire set is aimed at owners of GM LS-based V8 trucks, SUVs and performance cars from the late 2000s through 2020 who want a reliable, higher-temperature-tolerant replacement or an upgrade from worn factory wires. It suits DIY mechanics, performance hobbyists and fleet maintainers who need direct-fit compatibility, longer-lasting insulation and improved electrical delivery without modifying ignition components. If you drive one of the covered models and want a visible blue, durable plug wire set engineered to handle heat, vibration and modern ignition electronics, this kit is a practical choice.
