GDUKOP 9070C Spark Plug Wire Set for LS Engines — 8pc Ceramic-Jacketed Wires with 2500°F Thermal Sleeves

GDUKOP 8pcs 9070C spark plug wire set pairs ceramic-jacketed wires with 2500°F thermal protection sleeves to prevent boot melting and shorten downtime on LS3/LS4/LS7/LT engines.

This complete 8-wire kit is engineered for GM LS-family V8 applications where tight manifolds, crowded engine bays, or high exhaust temperatures have caused conventional boots to burn or fail. The set includes eight 6.1" boots, eight spark plug wires and eight basalt-layered titanium-colored heat shields rated to resist up to 2500 degrees Fahrenheit. It’s intended as a direct-fit, high-temperature protection upgrade for specified Cadillac, Chevrolet and GMC models that use LS-series terminals.

Will these wires fit my LS3, LS4, LS7 or LT engine?

Yes — the 9070C kit is built to be compatible with LS-series terminal fittings commonly used across many GM V8 models. Cross-check the listed vehicle years and models for fitment, and verify terminal types on your engine to ensure proper connection.

• Direct compatibility with LS-style terminals (LS3, LS4, LS7, LT).
• Vehicle examples: Corvette (2005–2008), Silverado (2007–2008), Escalade (2007–2008), and others listed in the fitment.
• Each boot measures 6.1" with 1.4" inner diameter for common LS plug bosses.

How does the 2500°F thermal sleeve protect my ignition components?

The kit’s heat shields use two layers of basalt fabric to form a ceramic-like barrier that resists extreme radiant and conductive heat. This reduces the chance of boot melt, wire hardening or insulation cracking when wires sit close to headers, manifolds or hot exhaust routing.

• Basalt-based two-layer construction for high-temperature resilience.
• Rated insulation up to 2500°F to block extreme radiant heat.
• Titanium-colored shield for corrosion resistance and long-term durability.

What performance and durability benefits should I expect?

Beyond preventing boot burn, ceramic jacketing and heat shields help maintain consistent insulation and dielectric strength over time, which supports reliable spark delivery. That means fewer misfires and less maintenance due to heat-related wire failure in high-load or confined engine applications.

• Ceramic-jacketed wires designed for extreme temperature environments.
• Reduced risk of burn-through and premature insulation failure.
• Package includes all eight wires and matching boots for a full-bank replacement.

How easy is installation and what comes in the package?

Installation follows standard plug-wire replacement steps and the kit comes complete for one V8 bank so no additional sleeves are required. The boots and wires are sized to fit LS plug locations and terminals, making swap-out straightforward for most DIYers and techs.

• Package: 8 spark plug wires, 8 boots (6.1" length, 1.4" ID), 8 heat shields.
• Direct-replacement wiring routing for listed GM models — no trimming needed.
• Recommended: confirm terminal type and routing before final installation.

Who is this for? This GDUKOP 9070C kit is aimed at owners and technicians working on GM LS-family V8s who face high under-hood temperatures, tight manifolds or recurring boot melt issues. It’s a practical upgrade for performance street cars, older vehicles with heat-damaged ignition boots, and motor enthusiasts who want a durable, heat-resistant ignition wiring solution that installs without modifying the engine harness.
