ENA 8-Pack UF413 Ignition Coil Kit with 8 Platinum Spark Plugs & Red 48322R Wires — For GM 4.8L–6.2L V8 (Square UF413, OE Fit)

This complete ignition kit from ENA groups the square UF413 coil packs, matched platinum-tip spark plugs, and heavy-duty red spark plug wires so you can replace all eight cylinders at once. The set is built to match OE-style fitment for many Chevrolet, GMC, Cadillac, Buick and Hummer models from the mid-2000s through the 2010s. Before ordering, confirm your vehicle uses the square UF413 coil design (not the round UF414) and check the listed reference numbers to ensure compatibility.

How do I know this kit fits my truck or SUV?

Fitment is determined by engine displacement and original coil type; this kit targets GM V8s in the 4.8L, 5.3L, 6.0L and 6.2L families used across Silverado, Sierra, Tahoe, Suburban, Avalanche, Express, Yukon, Savana, Corvette and Camaro model years listed. Use the part references and the online Confirmed Fit tool to verify compatibility. Also visually confirm your existing coil shape is the square UF413 style.

• Check part numbers: UF413, 12570616, 12611424 cross-references listed in the description.
• Compare coil shape: this kit is the SQUARE UF413, not the ROUND UF414.
• Use your VIN or model-year lookup on the retailer page to confirm exact fit.

What are the main technical features of the ENA coils, plugs, and wires?

The kit combines bolt-on 12V coil packs, platinum-center-electrode spark plugs with a 0.039" gap, and 8 mm silicone-insulated wires with nickel-chromium cores. Each coil mounts to the cylinder head and supplies reliable high-voltage output to the plug; wires are color-coded red for quick visual inspection. The components are designed for direct replacement and straightforward installation.

• Coils: 4-terminal bolt-on design, engine-head mounting, 12V operation.
• Spark plugs: platinum tip, 14 mm thread diameter, 5/8" hex size, 0.039" gap.
• Wires: 8 mm diameter, silicone insulation, nickel-chromium core for conductivity.

How hard is installation and what tools or steps are required?

Installation is typical for ignition service: remove old coils and wires, replace spark plugs, then install the new coils and wires. Basic hand tools and a torque wrench for spark plug tightening are recommended. The kit follows OE mounting and electrical connectors to minimize modifications.

• Tools: ratchet, spark plug socket (5/8"), torque wrench, dielectric grease recommended.
• Steps: remove battery negative for safety, swap plugs, replace wires matching cylinder order, install coils and torque bolts to spec.
• Tip: verify coil shape before purchase and route wires following original clips to avoid heat contact.

This ENA kit cross-references common OEM and aftermarket numbers so you can match it to service guides or parts lists. It lists replacement numbers for coils, plugs and wires and cites broad vehicle families across Chevrolet, GMC, Cadillac, Buick and Hummer lineups produced in the mid-2000s through 2016 for certain models. Always pair the references with the Confirmed Fit lookup for final assurance.

• Coil references: UF413, 12570616, 12611424 and related cross-numbers in the description.
