Ozikutech Spark Plug and Ignition Wire Kit for GM LS V8 - 8-Piece, Iridium Plugs & Shielded Black Wires

Ozikutech's 8-piece high-performance spark plug and ignition wire kit delivers reliable ignition for Chevy, GMC, Cadillac, Buick and Hummer LS-series V8 engines.

This complete set combines iridium-tipped spark plugs pre-gapped to 0.04" (1 mm) with heavy-duty black performance ignition wires built to suppress EMI/RFI and maintain low resistance. The kit is engineered as a direct-replacement service package for a broad range of GM LS-family engines across trucks, SUVs and performance cars—making a one-stop swap for tune-ups or maintenance.

Which vehicles and engines will these plugs and wires fit?

The kit is compatible with many GM models and years that use LS-series V8 engines. Fitment covers Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Express vans, Corvette, Camaro, and several Cadillac, Buick and Hummer models. Always confirm part numbers or engine code before purchasing.

• Common Chevy/GMC trucks and SUVs from late 1990s through mid-2010s (4.8L, 5.3L, 6.0L, 6.2L).
• Performance models like Corvette C5/C6 and Camaro across listed years and displacements.
• Vans and large SUVs (Express, Savana, Yukon XL, Suburban) with the compatible LS engines.

How do these components improve ignition consistency?

The iridium spark plugs and shielded wires are designed for steady spark delivery under varied conditions. The tiny iridium tip promotes a focused spark while the wires resist interference, together supporting smoother combustion cycles without claiming specific fuel economy or power gains.

• 0.04" (1 mm) pre-gap on plugs for consistent electrode spacing out of the box.
• Low-resistance wire construction reduces voltage loss between coil and plug.
• High EMI/RFI suppression helps prevent ignition noise affecting electronics.

What should I expect during installation and maintenance?

Installation follows standard spark plug and ignition wire replacement procedures and is suitable for DIYers comfortable with basic engine work or professional technicians. Use correct torque for plugs and route wires per factory guides to avoid crossfire or heat damage.

• Plugs arrive pre-gapped; verify gap before seating and torque to manufacturer spec.
• Match wire lengths and keep them away from hot exhaust or moving parts.
• Inspect boots and clamps for secure fit; replace any damaged connectors during install.

Are these parts direct replacements for OEM numbers?

Yes—the kit is manufactured to replace common OEM spark plug and wire part numbers used on GM LS engines. It’s sold as a complete eight-plug and eight-wire set to match factory configurations for V8 banks with coil-on-plug or distributorless setups where applicable.

• Designed to substitute multiple OEM references for LS-series GM engines.
• Sold as a matched eight-plug/eight-wire kit to simplify full-bank replacement.
• Compatible with typical GM ignition layouts—confirm engine family and year.

Who is this for: Mechanics, restoration enthusiasts and weekend DIYers who need a matched ignition tune-up kit for GM LS V8 applications will find this Ozikutech set convenient. It’s aimed at owners of Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Corvette, Camaro, Express/Savana vans, Cadillac Escalade, Buick Rainier/LaCrosse and Hummer H2/H3 models in the listed year ranges who want a single purchase to replace all eight spark plugs and wires at once.
