Ozikutech Spark Plugs and Wires Set of 8 for GM LS V8 — Iridium Plugs, Black Low-Resistance Wires

Ozikutech's 8-piece kit pairs iridium spark plugs with heavy-duty black performance wires engineered to restore crisp ignition and smoother throttle response on GM LS V8 engines.

This complete replacement set combines precision-gapped iridium plugs with low-resistance, EMI/RFI-suppressing wires designed for a direct fit on many Chevrolet, GMC, Cadillac, Buick and Hummer V8 models. Each plug is pre-gapped to 0.04" (1mm) and matched to durable silicone-jacketed wiring so you swap all eight connections at once and reduce misfires, rough idle and weak starts caused by worn ignition components.

Which vehicles and engines does this set fit?

The Ozikutech kit is built for GM small-block LS family engines across a wide range of full-size trucks, SUVs and performance cars. Fitment covers Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, Express vans, Corvette, Camaro, Escalade and select Buick, Pontiac and Hummer models from late 1990s through mid-2010s.

• Common LS displacements included: 4.8L, 5.3L, 5.7L, 6.0L, 6.2L and select 7.0L applications.
• Direct compatibility with many 1500/2500/3500 series trucks and full-size SUVs.
• Replaces multiple OEM part numbers used on LS1, LS2, LS3, LS6, L99 and related GM V8 engines.

How do these plugs and wires improve everyday driveability?

Sharper spark and cleaner wiring reduce engine hesitation, help maintain consistent RPMs at idle and can improve throttle response under load. Iridium tips sustain a stable spark gap longer than standard electrodes, while the wires’ low resistance lowers signal loss and interference.

• 0.04" pre-gap for reliable ignition timing right out of the box.
• High EMI/RFI suppression prevents electrical noise that can disrupt engine management sensors.
• Silicone-jacketed wires resist heat and abrasion for longer service life.

What are the build details and material highlights?

Each spark plug uses an iridium center electrode for long-term durability and a consistent arc. The accompanying wires feature thick, high-performance cores and reinforced boots to withstand under-hood temperatures and repeated routing across valve covers and coil packs.

• Iridium electrodes for extended wear and steady firing characteristics.
• Heavy-duty black cable with low electrical resistance.
• Durable boot ends engineered for secure coil and plug connections.

Is installation straightforward for DIY mechanics?

Yes—this kit is intended as a one-for-one swap with the factory spark plugs and wires on compatible LS engines. Replacing all eight plugs and wires together minimizes cross-firing risks and resets ignition performance to manufacturer-like standards.

• Pre-gapped plugs reduce tuning steps after installation.
• Wires are length-matched for correct routing and secure fitment.
• Fits common coil-pack and distributorless ignition arrangements used on LS engines.

Who is this for: The Ozikutech High Performance Spark Plugs and Wires Set of 8 is aimed at owners and technicians of GM LS-powered trucks, SUVs and performance cars who want a reliable, OEM-replacement-quality ignition refresh. It’s suitable for do-it-yourselfers who prefer a complete plug-and-wire change in one service interval, as well as professional shops servicing Silverado, Sierra, Tahoe, Yukon, Avalanche, Suburban, Express, Corvette, Camaro, Escalade, Hummer and related models. This kit suits vehicles showing misfires, rough idling, decreased responsiveness, or simply as scheduled ignition maintenance to preserve engine smoothness and drivability.
