ENA Round Ignition Coils for Chevy Silverado 1500 — 8-Pack UF414 Style, 12V Bolt-On

ENA 8-pack round ignition coils provide direct-replacement spark coil packs designed to fit a wide range of GM V8 vehicles, including Silverado 1500 models from 2007–2013.

These ENA ignition coils are a plug-and-play replacement set engineered to match the round UF414-style coils used on many GM V8 engines (4.8L, 5.3L, 6.0L, 6.2L and select 7.0L applications). Supplied as a complete kit of eight, the coils are intended for bolt-on installation at the valve cover and operate from a standard 12V system. Check part numbers and coil shape to ensure compatibility—this listing is for the round-style coil, not the square UF413 variant.

How do I confirm these are the correct coils for my truck?

Before ordering, compare the physical shape of your existing coils and confirm the part number compatibility. This ENA set is the ROUND UF414 style—if your original coils are square (UF413) these will not match. Also verify mounting type and terminal count with your vehicle.

• Confirm coil shape: round (UF414) not square (UF413)
• Check original part numbers against the ENA reference list
• Verify mounting: bolt-on to valve cover, 4 terminals, 12V
• Enter vehicle details in your garage or parts lookup to double-check fitment

Basic hand tools and a clean workspace are all that’s usually required; follow standard safety and service precautions for working on the ignition system.

• Tools: ratchet set, torque wrench (recommended), dielectric grease optional
