Ozikutech Iridium Spark Plugs & Ignition Wires Set for Chevy/GMC LS V8 4.8–6.2L — Pre-gapped, Direct-Fit

Ozikutech 41-110 Iridium Spark Plugs and Wires Set is a direct-fit ignition replacement engineered for GM LS-series V8 engines, offering a durable iridium tip and pre-gapped wiring to restore reliable spark across 4.8L, 5.3L, 6.0L, and 6.2L applications.

This complete set bundles iridium-tipped spark plugs and matched ignition wires designed to replace OE part numbers such as 41-110, 41-162, 41-985, 9602, 41-962, and GM references 19417055, 12621258, and 12680072. The kit suits a wide range of Chevrolet and GMC models built on the LS V8 family, plus compatible Buick, Pontiac, Cadillac, Hummer, and other GM-based vehicles. Each spark plug arrives pre-gapped to 0.04" (1 mm) so you can install with minimal prep, while the wires are sized to the factory routing to simplify fitment.

Will these plugs and wires fit my Chevy or GMC LS engine?

Yes—this set is made to cover many LS-series V8 engines across Chevrolet and GMC model years listed by Ozikutech. It replaces multiple OEM numbers and matches the spark plug thread, reach, and heat range requirements for the listed vehicles.

• Compatible with Silverado, Sierra, Tahoe, Yukon, Suburban, and more (1997–2018 ranges depending on model)
• Replaces OE numbers 41-110 / 41-162 / 41-985 and GM references cited by the manufacturer
• Covers additional GM cars like Corvette, Camaro, Impala, Avalanche, and Cadillac Escalade
• Also fits certain Hummer, Buick, Pontiac, and Pontiac-derived performance cars

How do these iridium plugs and wires improve ignition performance?

Iridium material and a fine center electrode produce a more focused spark than standard copper plugs, which improves consistency at each firing event. Combined with low-resistance, properly routed wires, the set reduces misfires and preserves strong combustion across RPM ranges.

• 0.04" (1 mm) pre-gap for consistent ignition out of the box
• Iridium tip for longer electrode life and stable spark energy
• Matched wire lengths and connectors for secure electrical transfer
• Designed to meet OEM thread size and torque specifications

What should I know about installation and maintenance?

Installation is straightforward for anyone comfortable with basic engine work: remove the old wires and plugs, confirm plug gap, and torque new plugs to the vehicle-specified setting. Inspect spark plug wells and coil boots for oil or debris before installing to ensure a clean connection and prevent cross-firing.

• Torque new plugs to manufacturer spec; avoid over-tightening
• Verify the 0.04" pre-gap before installation if your engine requires a different gap
• Replace one plug at a time to preserve ignition firing order and avoid mix-ups
• Check coil boots and wiring harness for damage during the swap

Which OE numbers and engines does this kit replace?

The Ozikutech 41-110 kit is intended as a direct replacement for a number of factory parts and covers the majority of GM LS small-block V8 variants. It's engineered to fit the listed Chevrolet and GMC model years and engine displacements without modification.
