Ozikutech 8 Pcs Iridium Spark Plugs – OEM Replacement for GM V8 (Chevy/GMC)

Engineered for GM V8 Performance

Power and reliability can transform every drive, especially when your GM V8 powertrain depends on clean, consistent ignition. Ozikutech 8-piece iridium spark plug set is designed to be a durable, ready-to-install upgrade that aligns with your engine’s original performance goals. The iridium construction supports precise, stable sparks across a wide range of GM platforms, from daily commutes to heavier loads.

Whether you’re cruising city streets or hauling cargo, these plugs are built to keep ignition steady and throttle response smooth. The result isn’t a guaranteed outcome, but a credible possibility of improved ignition consistency and efficient combustion when paired with proper maintenance and correct installation.

Compatibility Highlights

• Chevrolet: Silverado, Suburban, Tahoe, Express, Avalanche, Corvette, Camaro, and related 4.8L–8.1L V8 applications
• GMC: Sierra, Yukon, Savana, and related heavy-duty trucks and vans
• Cadillac, Hummer, Pontiac: Escalade family, GTO/Firebird/Grand Prix lineage, and compatible 5.3L–6.2L V8 engines

• Coverage spans model years from late 1990s through the mid-2010s, across multiple GM platforms
• Designed to work with LS1/LS2/LS3/LS6 and other GM LS-based V8 configurations

What’s in the Set and Key Features

• OEM replacement numbers include: 41-110, 41-162, 41-985, 9602, 41-962, 19417055, 12621258, 12680072
• Compatibility covers popular GM pickups, SUVs, and vans from 1999–2018 model years
• Iridium tips offer durability and consistent spark delivery over many miles
• 0.04 inch (1 mm) pre-gap provides a reliable starting point for ignition timing

In practice, an 8-piece set like this can contribute to smoother idle, steadier acceleration, and potentially better combustion efficiency under varied driving conditions. It’s a practical upgrade for those maintaining their GM V8 fleet and seeking a straightforward replacement that aligns with OEM references.

Installation and Use Scenarios

Ease of installation is a practical advantage for both DIY enthusiasts and professional mechanics. The pre-gap specification reduces one setup step, while the iridium construction aims to extend service intervals compared with traditional plugs. Real-world use may include:

• Quick replacement during routine maintenance or a scheduled tune-up
• Consistent ignition across cold starts in cooler climates
• Improved throttle response and stable idle in high-load scenarios

Keep in mind that results depend on the vehicle’s overall condition, supporting components, and correct torque when installing. This description emphasizes possibilities based on design and compatibility data, not guarantees.
