Pynccid Ignition Coil Kit for Chevy/GMC V8 1999-2007 — 8 UF262 Coils, 8 Spark Plugs & 8 8mm Wires (red)

Pynccid's all-in-one ignition kit bundles eight UF262 round ignition coils, eight 41-962 spark plugs, and eight 748UU 8mm spark plug wires as a direct-fit replacement for GM V8 trucks and SUVs from 1999–2007.

If your Silverado, Sierra, Tahoe, Suburban, Avalanche, Yukon, or Express with a 4.8L, 5.3L, or 6.0L V8 is running rough, misfiring, or showing a loss of throttle response, replacing the ignition components as a set restores consistent spark and makes diagnosis simpler. This Pynccid kit matches OEM form, fit and terminal locations for part numbers such as D585, 12573190, and 10457730, and includes everything needed for a full ignition refresh: coils, plugs, and high-quality wires.

How does this kit improve starting and engine smoothness?

The kit replaces worn coils, degraded spark plugs, and resistive wires with matched components to re-establish reliable spark timing and intensity. Better spark delivery reduces misfires, helps the engine return to steady idle, and often shortens cranking time on cold starts.

• Eight UF262 round coils engineered to match GM mounting points and electrical connectors.
• 41-962 spark plugs with consistent gap and electrode design for predictable ignition.
• 748UU 8mm silicone-insulated wires with carbon-impregnated cores for stable spark transfer.

Will these parts fit my 1999–2007 Chevy or GMC V8 vehicle?

Yes — the kit is designed for GM V8 engines with the round ignition coil configuration used across many 1999–2007 models. It is a direct replacement for the listed OEM numbers and requires no modification when your vehicle uses the UF262-style coil mount.

• Compatible with Chevy Silverado 1500–3500 and Tahoe/Suburban models of the period.
• Fits GMC Sierra, Yukon, and Express vans with 4.8L, 5.3L, or 6.0L V8 engines.
• Direct-fit terminals and mounting dimensions for a plug-and-play swap.

What are the construction and durability features of the components?

Components are built for higher thermal and electrical stress than basic replacements. Coils use copper windings and vacuum-sealed epoxy; wires use high-density silicone jacket and carbon-fiber cores; plugs are manufactured to consistent standards for longevity and stable gaps.

• Copper windings designed to withstand elevated engine temperatures up to 482°F.
• Vacuum-sealed epoxy and industrial-grade terminals to resist corrosion and vibration.
• Silicone-insulated 8mm wires for abrasion resistance and heat tolerance.

How simple is installation and what does the kit include?

This set is intended for straightforward replacement: remove the old coil, plug, and wire, and install the new parts in the same locations. The kit contains everything needed for a full eight-cylinder ignition service so you can avoid mismatched components and reduce troubleshooting steps.

• Eight round UF262 ignition coils that align with OEM mounting holes and connectors.
• Eight 41-962 spark plugs pre-specified for compatible GM engines.
• Eight 748UU 8mm spark plug wires with correct length and terminal ends for each cylinder.

Who is this kit for? Mechanics, professional techs, and do-it-yourself owners who want a complete ignition-system refresh for eligible Chevy and GMC V8 trucks and SUVs will find this Pynccid package practical. It removes the guesswork of mixing components, provides direct-fit parts for common GM OEM numbers, and supplies durable materials intended for long service life. If you're addressing misfires, poor throttle response, uneven idle, or replacing aging ignition parts across all eight cylinders, this all-inclusive kit offers a single purchase to restore consistent spark delivery and simplify installation.
