Ozikutech Iridium Spark Plugs and High-EMI Wires Set of 8 for GM LS V8 — Direct-Fit, Pre-Gapped

Ozikutech’s 8-piece set combines iridium spark plugs and heavy-duty black performance wires engineered to restore reliable ignition for GM LS-series V8 engines.

If your Chevy, GMC, Cadillac or compatible GM vehicle runs on an LS-series small-block, this set replaces worn ignition components with factory-fit spark plugs and high-EMI suppression wires. The kit is designed for direct replacement on many Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, Express, Corvette, Camaro and other GM models from late 1990s through mid-2010s, giving a one-stop service solution for eight-cylinder ignition banks.

Which vehicles and engine models will this kit fit?

The set lists extensive compatibility with Chevrolet, GMC, Cadillac, Buick and Hummer models that used LS-family engines. Check engine displacement and model year ranges against your VIN or service manual because fitment covers many 4.8L, 5.3L, 5.7L, 6.0L and 6.2L applications.

• Chevrolet: Silverado, Tahoe, Suburban, Avalanche, Express, Camaro, Corvette, Impala
• GMC: Sierra, Yukon, Savana, Envoy
• Cadillac/Buick/Hummer: Escalade, CTS, Rainier, LaCrosse, H2/H3 models
• Common LS family coverage: LS1, LS2, LS3, LS6, L99 and similar V8 GM engines

How are these spark plugs and wires built to perform?

The spark plugs use a fine iridium tip with a 0.04" (1 mm) pre-gap to provide consistent, repeatable spark behavior under varying engine loads. The performance wires are heavy-duty, black insulated cables designed with high EMI/RFI suppression and low electrical resistance to minimize interference and energy loss.

• Iridium electrodes for long life and stable gaps
• 0.04" (1 mm) pre-gapped plugs ready for most OEM installations
• High-suppression wires reduce ignition noise and misfires
• Durable jacket and boots for heat and abrasion resistance

Will this set replace my OEM part numbers?

Yes, the kit is intended as a direct replacement covering many OEM reference numbers used across GM small-block V8s. It matches the spark plug thread size and wire connector types typically found on LS engines, simplifying installation without vehicle modifications.

• Designed to replace commonly referenced OEM numbers for LS engines
• Includes eight plugs and eight wires for a complete V8 ignition bank service
• Direct-fit connectors and boot lengths for many stock routing layouts
• Pre-gapped plugs reduce installation prep time

How should I install and maintain this ignition kit for best results?

Install using the vehicle’s recommended torque specifications and anti-seize or thread lubricant only if specified by your service manual. Replace one wire at a time to maintain firing order and use dielectric grease in boot faces to prevent moisture intrusion. Regular visual checks and periodic gap inspections keep the ignition system functioning reliably.

• Follow OEM torque specs for spark plug installation
• Replace one wire at a time to preserve correct firing order
• Use dielectric grease in boots to prevent corrosion and moisture
• Inspect wires and boot seals during routine tune-ups

Who is this for? Ozikutech’s spark plug and wire set is aimed at DIY mechanics, independent shops and enthusiasts who maintain GM LS-family V8 vehicles and need a full eight-cylinder ignition renewal. If your Silverado, Sierra, Tahoe, Yukon, Corvette, Camaro, Escalade or related model falls within the listed years and engine sizes and you want a single kit that covers both plugs and wires, this is a practical, cost-effective replacement option that streamlines routine ignition service without changing engine electronics or wiring harnesses.
