ENA Ignition Wire and Platinum Spark Plug Set for GM V8 1999–2009 — Red 8mm Wires, 8-Piece Kit

ENA's complete set pairs eight platinum spark plugs with eight red 8mm silicone wires engineered to replace worn ignition components on select Chevrolet, GMC and Cadillac V8 trucks and SUVs from 1999–2009.

This kit bundles everything needed to refresh the ignition system on multiple GM V8 applications, offering OE-style fitment, platinum electrodes for steady sparking and silicone-insulated wires for heat resistance and reliable conduction. It's supplied as a plug-and-play replacement with part-number cross-references to simplify matching and a 12-month warranty for added confidence.

Which vehicles and engines will this ENA set fit?

The set supports a wide range of GM full-size trucks and SUVs with V8 engines between 4.8L and 8.1L manufactured roughly 1999–2009. Fitment covers Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche and Escalade variants; always confirm year, engine size and cab/bed configuration when checking fit.

• Supports 4.8L, 5.3L, 6.0L and selected 8.1L V8 engines in listed models.
• Cross-references OE numbers including 41962, 19299585, 41-962 and wire refs 88894394, 19417607.
• Use seller fit tools (e.g., Amazon Confirmed Fit) with your VIN for exact compatibility.

How does this kit improve ignition performance and durability?

The platinum-tipped plugs deliver consistent spark timing and resist electrode wear longer than plain copper tips, while the 8mm silicone wires provide improved insulation against heat and arcing. Together they stabilize combustion behavior and reduce misfire risk when installed correctly.

• Platinum center electrode with a 0.039" gap for steady spark delivery.
• Wire-wound core and silicone insulation for thermal and electrical reliability.
• Red 8mm wires for clear routing and durable high-voltage transmission.

What are the technical specifications and what's included?

The package contains eight platinum spark plugs and eight red ignition wires sized for GM V8 routing. Specifications list a 14mm thread diameter plug, 0.63" hex, and wires with an 8mm diameter silicone jacket and wire-wound core for conductivity.

• Spark plug: platinum tip, 0.039" gap, 14mm thread, 0.63" hex.
• Spark plug wire: 8mm diameter, wire-wound core, silicone insulation in red.
• Complete set for eight cylinders plus a 12-month warranty and installation-ready connectors.

How easy is installation for a DIYer or a professional mechanic?

These components are manufactured for direct replacement of factory parts and typically install without modification, making them suitable for competent DIYers and techs. Basic tools, a torque wrench for plugs and attention to firing order will ensure proper installation and reliable operation.

• Plug-and-play connectors match OEM routing and terminals.
• Follow torque specs and gap checks when fitting plugs.
• Replace wires one at a time to maintain correct cylinder order.

Who this product is for: This ENA set is intended for owners and technicians working on late‑1990s to late‑2000s GM full‑size trucks and SUVs with V8 engines who need a full ignition refresh. It's ideal when replacing an entire ignition lead system and plugs together—especially for vehicles showing age-related misfires, worn plugs, cracked boots or degraded insulation. Always verify vehicle fit with your year, engine displacement and VIN before purchase to ensure this kit matches your application.
