Ozikutech Iridium Spark Plugs & Wires Set — 8‑Piece for 1999–2013 Chevy/GMC LS V8, 1mm Pre‑Gapped with Heavy‑Duty Red Wires

Ozikutech high-performance iridium spark plugs and heavy-duty ignition wires give LS-series Chevy and GMC V8 engines a precise, durable ignition upgrade in an easy 8-piece kit.

If you're replacing worn ignition components or want a reliable performance upgrade for older GM V8 trucks, SUVs and performance cars, this complete set supplies eight 0.04" (1 mm) pre-gapped iridium spark plugs plus matched high-EMI/RFI suppression wires. The kit is designed to fit a broad list of Chevrolet, GMC, Cadillac, Buick, Pontiac and Hummer models with 4.8L–7.0L engines built between the late 1990s and the mid 2010s, offering a direct-replacement form factor and plug-wire pairing that simplifies installation.

Which vehicles will these plugs and wires fit?

This Ozikutech set covers many GM LS-series V8 applications across trucks, SUVs, and performance cars. It lists exact year ranges per model family so you can confirm compatibility before purchase.

• Chevrolet: Silverado (1999–2013), Tahoe (2000–2014), Avalanche (2002–2013), Suburban (2000–2014), Express series (2003–2018) and select Corvette/Camaro years.
• GMC: Sierra and Yukon families (2000–2018 depending on model), Savana vans, and select Envoy years.
• Other: Cadillac Escalade lines, Buick Rainier/LaCrosse, Hummer H2/H3, Pontiac GTO/Grand Prix where listed.

How does the iridium plug and wire combination improve ignition performance?

Iridium electrodes are harder and maintain a precise gap longer than conventional materials, which helps sustain consistent spark energy over time. Matched wires offer high EMI/RFI suppression and low resistance so ignition signal integrity stays strong, especially important on modern engine management systems.

• 0.04" (1 mm) pre-gap on plugs for consistent spark timing out of the box.
• Iridium center electrode resists wear and extends service life.
• Heavy-duty red cables with high EMI/RFI suppression reduce interference with sensors and radios.

What should I expect during installation and maintenance?

The kit is designed as a direct replacement for the listed OEM part numbers and installs using standard hand tools. Always inspect ignition boots and wire routing, replace one bank at a time if necessary, and torque plugs to manufacturer specs to ensure proper sealing and longevity.

• Direct-replacement fit for specified GM OEM numbers—no custom modifications required.
• Replace spark plugs and wires together to avoid mixing old components with new ones.
• Follow factory torque specs and check connector seating to prevent misfires.

Are these parts durable enough for daily driving and towing?

Yes; the combination of iridium electrodes and heavy-duty wire construction is built to withstand routine use, higher-load driving and typical towing demands common to trucks and SUVs. While durability depends on operating conditions, the materials and suppression design help maintain reliable ignition over longer service intervals than standard copper plugs.

• Iridium electrodes resist erosion under repeated firing cycles.
• Low-resistance wires maintain strong spark under load and high RPMs.
• Suitable for everyday driving, hauling, and occasional spirited use.

Who is this for: owners and mechanics of GM LS-series V8 vehicles—especially Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, Express vans, Corvette and Camaro models—who want a straightforward, cost-effective ignition upgrade. It's aimed at people replacing worn plugs and wires or those seeking improved spark stability without changing engine management hardware. Confirm fitment with your vehicle's year, engine size and OEM part numbers before ordering.
