Cable Master 10.2mm Racing Spark Plug Wires for GM Gen V V8 — Blue, Kevlar Core & Nickel-Wound Conductor

Cable Master 10.2 mm racing spark plug wires are a high-temperature, low-resistance ignition set engineered to replace OEM leads on select 5.3L, 6.2L and 6.6L V8 GM engines from 2014–2022.

These performance ignition cables pair a durable kevlar core and nickel-wound conductor with double silicone jacketing and reinforced fiberglass layering to improve voltage delivery and resist heat, oil and abrasion. They arrive in a vivid blue finish that matches many performance builds and fit a long list of Chevy and GMC models — from light trucks to performance cars — built on the Gen V small-block V8 family. The set is designed for technicians and enthusiasts who want reliable spark transfer, improved RFI suppression and longer service life than many stock leads.

Which vehicles and engines does this wire set fit?

This Cable Master set is made for vehicles using GM’s Gen V small-block V8s, including 5.3L, 6.2L and 6.6L applications across model years 2014–2022. Compatibility covers sedans, trucks, SUVs and vans listed specifically for CT5, CTS, Escalade, Camaro, Corvette, Express, Silverado, Suburban, Tahoe, Savana, Sierra and Yukon families.

• Engine sizes: 5.3L (325), 6.2L (376), 6.6L (401).
• Model years: 2014–2022 for most listed vehicles; verify exact trim fitment.
• Replaces part numbers like 758EE, 758DD, 19301299, 12633447.

How do these wires improve ignition performance?

The combination of a kevlar-reinforced core and a nickel wire-wound conductor lowers resistance and sustains higher spark energy to the plugs. Superior silicone jacketing and heat-resistant insulation maintain consistent performance under elevated underhood temperatures while reducing electromagnetic interference.

• Nickel-wound conductor for low resistance and steady voltage transfer.
• Double silicone jacket with fiberglass layer for heat and abrasion protection.
• Enhanced RFI suppression protects sensitive onboard electronics.

What materials and construction details matter to mechanics?

These wires use a kevlar core for tensile strength and a durable nickel-wound conductor to balance conductivity with flexibility. Boots and outer jackets are premium silicone to resist cracking, oil exposure and high temperatures common in modern V8 engines.

• Kevlar core increases durability and resists stretch during installation.
• High-tear-strength double silicone jacketing prevents leaks and abrasions.
• Heat-resistant insulation and robust boots for long service life.

How easy is installation and what should I check during fitment?

Installation follows the stock routing on compatible GM engines; the set includes boots shaped to match factory contacts. Confirm engine displacement and model year against part compatibility lists and inspect the boot seating and terminal alignment during installation for a secure connection.

• Match wire lengths to originals and maintain firing order routing.
• Ensure boots fully seat on spark plug and coil towers to avoid misfires.
• Check for interference with nearby harnesses or moving parts after fitment.

Who this is for: This Cable Master ignition wire set is aimed at performance-minded DIYers, professional mechanics and fleet technicians replacing worn leads on Gen V small-block Chevy/GMC V8s. Choose this kit if you want improved spark conductance, stronger resistance to heat and abrasion, superior RFI suppression, and an attractive blue jacket that complements engine-bay upgrades. Always verify specific vehicle and engine compatibility before purchase.
