GDUKOP 9070C Spark Plug Wire Set for GM LS Engines - 8pc with 2500F Ceramic & Basalt Heat Shields

GDUKOP 8pcs 9070C spark plug wire set combines ceramic-jacketed wires and 2500°F thermal protection sleeves to protect LS-series engines from heat-related boot failure and ignition damage.

These replacement ignition wires are built for GM LS family motors (LS3, LS4, LS7, LT) and many Chevy, GMC and Cadillac models listed in the fit guide. The kit addresses common failures caused by extreme under-hood temperatures and tight-clearance manifolds by pairing ceramic-insulated wire boots with basalt-fiber heat shields rated to endure intense heat. The set includes eight wires and matching high‑temperature boot covers engineered to resist melt-through, cracking and premature aging.

How do these wires withstand high engine temperatures?

GDUKOP uses a ceramic jacket on the wire boots plus a two-layer basalt heat shield to block radiant and conductive heat. Those materials are rated up to 2500°F, reducing the chance of melted boots or burned insulation in hot zones.

• Ceramic-jacketed boots resist softening and deformation at extreme temperatures
• Basalt two-layer shields deliver thermal and corrosion resistance
• Heat shields slip over boots to prevent direct exposure to manifolds or headers

Will this set fit my vehicle with an LS-series engine?

The 9070C kit is designed to be compatible with a range of GM models using LS3, LS4, LS7 and LT terminals; check the included fit list for exact model years. Wires come pre-cut to common lengths and include eight ceramic boot covers to match typical V8 layouts.

• Direct fit for many 2005–2008 Chevy, GMC and Cadillac V8 models listed in the fit guide
• Supplied wire count and lengths for standard LS ignition layouts
• Compatible with LS-style terminals and common GM plug spacing

How does installation and durability compare to stock wires?

Installation follows the same routing and terminal connections as OEM wires, but the reinforced sleeve and ceramic boots improve longevity in hot or confined engine bays. These upgrades minimize boot failures and electrical insulation breakdown that can cause misfires or arcing.

• OEM-style terminals for straightforward connection to coils and plugs
• Slip-on ceramic sleeves make it simple to add thermal protection over existing boots
• Designed to resist cracking, hardening and burn-through over long service life

What components are included and what should I inspect before fitting?

The kit contains eight spark plug wires and eight 2500°F-rated ceramic/ basalt boot sleeves sized for common LS plug boots (approx. 6.1" length, 1.4" ID). Before fitting, confirm terminal fit, wire length routing, and inspect coil/plug connections for corrosion.

• 8 spark plug wires matched to typical V8 layouts
• 8 ceramic/ basalt heat sleeves (6.1" length, 1.4" inner diameter)
• Verify terminal compatibility and wire routing prior to final installation

Who is this for: Drivers, mechanics and performance enthusiasts who run LS-series GM engines and need a robust ignition wire solution for high-heat conditions—such as tight manifolds, forced-induction setups, motorsport use, or older vehicles with deteriorating stock boots. This GDUKOP set is aimed at anyone seeking to reduce boot failures, extend wire life and maintain reliable ignition under elevated temperatures.
