ENA Round Ignition Coil UF414 for Chevy Silverado 1500 — Single Bolt-On 12V Coil Pack

ENA Round Ignition Coil (UF414) is a direct-fit, bolt-on coil pack engineered to replace failed round ignition coils on many GM V8 engines, restoring reliable spark and drivability.

If your V8-equipped Chevy, GMC, Cadillac or other GM vehicle is misfiring, running rough, or triggering a check engine light, a worn ignition coil is a common cause. This ENA coil is the round-style replacement (UF414 family) designed for plug-and-play swapping on numerous 4.8L, 5.3L, 6.0L, 6.2L and select 7.0L models from the mid-2000s through the late 2010s. It ships as a single coil pack, mounts to the valve cover with a bolt, and uses a 12V electrical connection matching OE-style terminals.

Which vehicles does this ENA round ignition coil fit?

This coil fits a wide range of GM vehicles that use the round UF414-style ignition coils. Fitment covers many Chevy Silverado and GMC Sierra trucks, full-size SUVs like Tahoe and Yukon, vans and performance cars such as the Corvette and Camaro across multiple model years and V8 displacements.

• Chevy Silverado 1500 (2007–2013) 4.8L/5.3L/6.0L/6.2L; Silverado HD and Avalanche fits listed
• GMC Sierra 1500/2500/3500 models (2007–2018) with compatible V8 engines
• Full-size SUVs and vans: Tahoe, Suburban, Yukon, Savana, Express, Escalade
• Performance models: Corvette (2006–2013 ranges) and Camaro 6.2L (2010–2015)

How easy is installation and what should I verify before ordering?

Installation is straightforward for anyone comfortable with basic engine bay work: the coil bolts to the valve cover and plugs into the factory harness. Before purchasing, confirm your original coils are the round UF414 style (not the square UF413); the two types are not interchangeable.

• Plug-and-play design with OE-style connector and mounting
• Bolt-on mounting location on the valve cover—no special tools required
• Confirm part numbers or visually compare coil shape (round UF414 vs square UF413)
• Sold as a single coil pack—buy quantity matching number of failed coils

What are the key technical details and compatibility notes?

The ENA coil uses a 12V electrical system, four terminal contacts and a bolt-on mount. It’s designed to reproduce consistent spark energy for reliable combustion, and is listed under several cross-reference numbers for easier identification with existing parts.

• Terminal count: 4; Mount type: bolt-on; Mount location: valve cover
• Voltage: 12V; Designed for V8 engines 4.8L–7.0L where UF414 fits
• Reference numbers include UF414, C1512, D514A, 12699382 and others
• Comes as one coil pack with a 12-month limited warranty

How will replacing a failed coil improve vehicle performance?

Replacing a degraded ignition coil can clear misfires, smooth idle, and reduce hesitation during acceleration when the failure is coil-related. While coil replacement addresses ignition-related drivability issues, always diagnose fault codes and inspect spark plugs and wiring for a complete repair.

• Reduces cylinder misfires and related vibration
• Helps restore consistent throttle response and engine smoothness
• Works best when paired with correct spark plugs and healthy wiring

Who is this for: This ENA round ignition coil is aimed at owners and technicians maintaining GM V8 vehicles that require the UF414 round-style replacement—DIY mechanics replacing a single failed coil, fleet maintainers needing an economical OE-style part, and professional shops seeking a compatible coil pack for a broad range of Chevy, GMC, Cadillac, Hummer, Pontiac and related models. Verify your vehicle’s coil shape and part references before ordering to ensure proper fitment.
