Ozikutech spark plug and wire kit for Chevy GMC LS V8 — Set of 8, iridium plugs & 10.2mm suppression wires

Ozikutech’s 8-piece spark plug and ignition wire kit is a direct-fit ignition upgrade for LS-series V8 GM engines designed to deliver consistent spark, improved electrical suppression, and reliable fitment across many Chevy, GMC, Cadillac, Buick, Pontiac and Hummer models.

This complete kit pairs precision iridium spark plugs with heavy-duty 10.2mm ignition cables to replace worn ignition components on LS family V8s. Each plug is pre-gapped to 0.04" (1 mm) and the wires include high EMI/RFI suppression and low resistance conductors for stable ignition under load. The set fits many popular GM trucks, SUVs and performance cars from the late 1990s through the 2010s, making it an economical service option for routine tune-ups or restoration projects.

Will this set fit my Chevy Silverado or GMC Sierra LS V8?

Compatibility covers a broad range of model years and engine displacements for Silverado and Sierra variants equipped with LS V8 engines. Check your vehicle’s model year and engine code to confirm, but the kit is intended specifically for many 4.8L, 5.3L, 6.0L and 6.2L GM V8 applications.

• Fits Chevy Silverado 1500 (1999–2013) and Classic 1500 (2007) across multiple displacements.
• Compatible with Sierra 1500 (2000–2013), Sierra 2500 HD (2001–2013) and Sierra 3500 HD (2001–2018).
• Includes support for 2007-model Classic trucks and many 6.0L heavy-duty derivatives.

What are the technical advantages of the plugs and wires included?

The spark plugs use an iridium fine electrode and a factory pre-gap to maintain consistent ignition performance over a long service life. The ignition wires are built with a 10.2mm diameter core that minimizes resistance and suppresses electromagnetic interference, improving coil and ECU reliability.

• Iridium plugs pre-gapped to 0.04" (1 mm) for consistent firing.
• 10.2mm heavy-duty wires with high EMI/RFI suppression.
• Low-resistance design reduces energy loss between coil and plug.

How easy is installation and what OEM numbers does it replace?

This kit is designed as a direct-replacement set for factory-style plug-and-wire assemblies on compatible LS engines, so most home mechanics can install it with common hand tools and basic ignition removal technique. The listing references many OEM part numbers to help confirm fitment before purchase.

• Direct-fit plug-and-wire kit for LS1, LS2, LS3, LS6 and L99 platforms.
• Replaces numerous OE references like 12192133, 12622553, 19301299 and others for quick cross-checks.
• Installation requires spark plug socket, ratchet and care removing wire boots from coils.

Which other GM models are covered by this ignition set?

Beyond Silverado and Sierra trucks, the kit supports many GM SUVs, vans and performance cars that used LS-family V8s. Compatible examples include Tahoe, Suburban, Avalanche, Express vans, Corvette, Camaro, Escalade, Yukon, Savana, Buick Rainier/LaCrosse, Hummer H2/H3, Pontiac GTO and select Impala and SSR years.

• Chevy: Tahoe, Avalanche, Suburban, Express, Corvette, Camaro, Impala, SSR.
• GMC: Yukon, Savana, Envoy, Canyon-compatible years listed.
• Cadillac/Other: Escalade, CTS, Rainier, LaCrosse, Hummer and Pontiac listings.
