AiYiGu 8-Piece UF413 Ignition Coil Kit with 8mm Red Spark Plug Wires & Iridium Plugs — Chevy/GMC 4.8L–6.2L V8 Direct-Fit

AiYiGu 8-piece UF413 square ignition coil set with eight 8mm red spark plug wires and eight iridium/platinum spark plugs — a direct-fit replacement for many Chevy, GMC, Cadillac and Buick 4.8L–6.2L V8 engines.

When an engine misfires, rough idle or poor throttle response points to ignition components, replacing the coils, plug wires and spark plugs as a matched kit restores consistent spark delivery and reduces troubleshooting. This AiYiGu kit groups the eight square UF413-style ignition coils, eight red high-dielectric 8mm spark plug wires and eight long-life iridium/platinum spark plugs for one-pass maintenance on common GM V8 platforms. All components are manufactured to meet or exceed OE dimensions so they install quickly without modification.

Will this kit fit my Chevrolet or GMC V8?

Compatibility covers a wide range of GM vehicles with 4.8L, 5.3L, 6.0L and 6.2L V8 engines. Always compare the part numbers, mounting style and electrical connector shapes shown in your vehicle’s service manual or the listing compatibility chart before ordering. If your OEM coil uses the UF413/12570616-style footprint, this kit is intended as a direct replacement.

• Fits models including Silverado, Suburban, Tahoe, Sierra, Yukon, Avalanche, Camaro, Corvette and more.
• Replaces OE numbers such as UF413, 12570616, 12611424, GN10165 and equivalents.
• Check the listing’s fitment chart and connector photos for confirmation.

How do these coils and wires improve ignition reliability?

The AiYiGu coils are engineered to match OE electrical characteristics and pinout while using reinforced insulation to resist heat and vibration. The 8mm wires feature a high-dielectric core and robust boots to reduce crossfire and arcing, ensuring more consistent spark under load. Together with the iridium/platinum plugs these parts restore stronger, more stable combustion.

• Coils built to OE dimensions for proper seating and thermal endurance.
• Red 8mm wires minimize EMI and arcing with secure boot connections.
• Iridium/platinum plugs deliver longer service life than standard copper types.

What should I expect during installation and service life?

Installation is straightforward for anyone comfortable removing valve covers and unplugging coil connectors; professional installation is recommended if you lack experience. The kit is sold as a full eight-cylinder replacement so you replace all ignition items at once, reducing the chance of repeat failures. AiYiGu provides a 12-month warranty covering manufacturing defects.

• Direct-fit design reduces modification — bolt-on and plug-in replacement.
• Replacing all eight coils, wires and plugs lowers diagnostic time and repeat visits.
• 12-month warranty; keep purchase records and install receipts for claims.
