Ozikutech Iridium Spark Plugs and Red Ignition Wires Kit for GM LS V8 (8‑Pack) — Pre‑Gapped 0.04", Low‑Resistance Cables

Ozikutech's 8-pack iridium spark plugs and red high‑performance ignition wires are a direct-fit upgrade for many GM LS V8 vehicles from 1997–2018, engineered for reliable, consistent ignition and long service life.

This complete ignition set pairs fine‑wire iridium plugs with heavy‑duty, low‑resistance ignition cables to replace worn factory parts on Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Express, Corvette, Camaro and other compatible GM models. The kit is built for vehicles using LS family 4.8L, 5.3L, 5.7L, 6.0L and 6.2L engines and includes plug pre‑gapped to 0.04" (1 mm) to help simplify installation.

How do these iridium plugs and wires improve ignition performance?

The iridium center electrode, combined with a precise 0.04" pre‑gap, promotes a stable and efficient spark under a range of engine loads. Paired with low‑resistance, EMI/RFI‑suppressed cables, the set reduces electrical interference and supports consistent firing across all cylinders.

• Iridium tip for longer electrode life and steady spark characteristics.
• Pre‑gapped to 0.04" (1 mm) to match recommended clearances for many LS engines.
• High EMI/RFI suppression cables cut radio and sensor interference.
• Heavy‑duty red cable jacket resists heat and abrasion in engine bays.

What should I expect during installation and maintenance?

Installation is straightforward for anyone comfortable with basic engine work; the set replaces eight plugs and all ignition leads in one service. Use a torque wrench on plugs to the vehicle manufacturer’s specification and route cables to avoid contact with exhaust components or sharp edges.

• Plugs come pre‑gapped—verify gap before installation and torque to spec.
• Replace wires one at a time to preserve firing order and routing.
• Inspect boots and connectors for fit; secure clamps or retainers as needed.
• Recommended as a preventive maintenance upgrade at moderate mileage or when diagnosing misfires.

Are these parts OEM or aftermarket replacements?

This Ozikutech kit is a high‑quality aftermarket replacement engineered to meet or exceed OEM fitment and electrical performance for GM LS engines. It provides a cost‑effective way to refresh an ignition system without changing ignition timing or engine controls.

• Aftermarket direct‑fit components engineered for LS V8 GM engines.
• Designed to replace multiple OEM part numbers listed in the product details.
• No ECU reprogramming required for plug/wire swaps in compatible vehicles.

Who is this for: This ignition upgrade suits DIY mechanics, independent shops and fleet owners who need a reliable 8‑cylinder plug and wire replacement for GM LS V8 vehicles. Choose this set if you want longer‑wear iridium plugs, stronger cable suppression, and a single kit that covers all eight cylinders for common Chevy, GMC, Cadillac, Buick, Pontiac and Hummer applications.
