Ozikutech High‑Performance Spark Plug Wires Set for Chevy GMC V8 — 8‑Pack 10.2mm Low‑Resistance EMI‑Suppression

Ozikutech's 8-pack high-performance spark plug wires are a direct replacement wiring set engineered for V8 Chevy and GMC engines from late‑1990s through 2021 to restore reliable ignition and reduce electrical interference.

These spark plug wires are built for modern LS-series and related V8 engines used across Chevy, GMC, Cadillac, Buick, Pontiac and Hummer models. The set replaces worn or damaged wires with a heavy‑duty 10.2mm conductor design that focuses on low resistance and strong EMI/RFI suppression. Each kit comes ready to install as a full eight‑wire harness to match factory routing and firing order for compatible vehicles.

Which engines and vehicles does this Ozikutech set fit?

This set fits many 4.8L, 5.3L, 5.7L, 6.0L, 6.2L and 7.0L V8 applications across GM platforms from the late 1990s through 2021. Compatibility covers mainstream trucks, SUVs, performance cars and vans, including Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, Express, Corvette, Camaro and others.

• Chevrolet: Silverado 1500/2500/3500 (1999–2021), Tahoe (2000–2020), Suburban (2000–2014), Corvette C5–C7 (1997–2019), Camaro (1998–2019)
• GMC: Sierra 1500/2500/3500 (1999–2021), Yukon/Yukon XL (2000–2021), Savana (2003–2018)
• Also fits select Cadillac, Buick, Pontiac and Hummer V8 models and multiple Express/van configurations (see full fitment list).

How does this set improve ignition performance on my V8?

The wires use a thicker 10.2mm conductor and materials tuned to lower electrical resistance while blocking electromagnetic and radio frequency noise. This helps maintain a stable spark under load, improving combustion consistency and throttle response compared with brittle or corroded factory wires.

• Heavy‑gauge 10.2mm cable for consistent conductivity.
• High EMI/RFI suppression minimizes ignition noise affecting electronics.
• Low-resistance design helps preserve spark energy at the plug.

Are these wires a direct replacement for factory part numbers?

Yes — the kit is manufactured as a direct-fit replacement for a long list of OEM and aftermarket references so you can swap them without modifying routing or terminal orientation. The set matches common GM plug wire lengths and terminal types used across compatible V8 models.

• Replaces OEM/aftermarket references: 48322, 48322R, M8-48322, 12192133, 12716289 and others listed.
• Eight-piece set corresponds to standard V8 firing order and plug spacing.
• Designed to fit original brackets and boots for straightforward installation.

What should I expect during installation and maintenance?

Installation is a straightforward swap-out: disconnect one wire at a time to preserve firing order, route to match factory clips, and ensure boots fully seat on the coil and spark plug tips. Wires require little maintenance beyond periodic inspection for cracks, heat damage or loose connections.

• Simple plug-and-play replacement—no special tools required.
• Inspect boots and terminals for secure, snug fit at both ends.
• Replace as a full set to avoid mismatched electrical characteristics.

Who is this for: Drivers and technicians who own GM V8 vehicles and want a reliable, cost‑effective ignition wire replacement that matches factory fitment while improving noise suppression and spark consistency. Ideal for owners of Silverado, Sierra, Tahoe, Yukon, Corvette, Camaro, Express vans and related GM SUVs/trucks who need an eight‑wire set tuned for 4.8–7.0L V8 engines.
