ENA Round Ignition Coil Pack UF414 — Set of 8 for Chevy/GMC 5.3L V8, Direct Replacement, Bolt-On

If your V8 is misfiring, rough at idle, or throwing coil-related codes, this ENA coil pack set offers a plug-and-play swap that matches the round UF414 style used on many GM 4.8L, 5.3L, 6.0L, 6.2L and select 7.0L engines. Each coil mounts to the valve cover with the factory-style bolt pattern and electrical connector, so replacement is straightforward for DIYers and technicians. The kit ships as eight coils so you can refresh an entire bank or the full engine at once for even performance.

How will these coils affect vehicle drivability?

Replacing worn or failing coils with ENA UF414 units helps eliminate intermittent misfires, improves throttle response, and reduces rough idle events caused by inconsistent spark. Because all eight coils are included, you avoid troubleshooting which cylinder is causing the issue and restore uniform ignition across the engine.

• Replaces failing coils to stop misfire codes (P0300–P0308 range)
• Restores even fuel burn and smoother idling
• Improves throttle feel and acceleration consistency
• Includes full set to prevent repeated disassembly

Will these coils fit my Chevy, GMC, or GM vehicle?

These coils are the round-style ENA UF414 and are compatible with many GM V8 models across multiple years. Fitment spans numerous Silverado, Sierra, Tahoe, Suburban, Yukon, Corvette, Camaro and other GM vehicles—confirm the original coil on your engine is the round UF414 design rather than the square UF413 variant before ordering.

• Commonly fits 4.8L, 5.3L, 6.0L, 6.2L and select 7.0L GM V8 engines
• Works with many Silverado/Sierra, Suburban, Tahoe, Yukon, Corvette and Escalade years
• Bolt-on mounting at valve cover with factory-style terminal and connector
• Verify part references (UF414, 12699382, 12573190, etc.) for exact match

What are the installation and specification details?

ENA round coils are sold as a set of eight, each with four terminals and a 12V rating, designed to install using the stock bolt locations. The coils are manufactured for direct replacement—no modification to wiring harnesses or adapters required—so installation is typically quick for someone familiar with basic engine work.

• Package includes: set of 8 round ignition coils (UF414 style)
• Specifications: 4 terminals, 12V operation, bolt-on valve cover mount
• Plug-and-play electrical connector and factory mounting footprint
• Comes with a 12-month warranty from ENA for peace of mind

How do I confirm I need the round UF414 rather than the square UF413?

Physically inspect one of your existing coils: the ENA UF414 is round-bodied where it meets the spark plug tube and uses the bolt-on valve cover mount. If your original coil is square/rectangular in cross-section, you likely have the UF413 type, which is not compatible with this kit.

• Compare shape: ENA UF414 = round housing; UF413 = square housing
• Check OEM/reference numbers printed on the old coil against UF414 codes
• Review vehicle-specific fitment lists or enter VIN for confirmation
• If unsure, remove one coil for a visual match before purchase

Who this is for: This ENA UF414 eight-coil pack is aimed at owners and technicians who want a cost-effective, full-bank replacement for GM V8 engines that use round ignition coils. It suits DIY mechanics refreshing all cylinders at once, shops performing tune-up services, and fleet managers who prefer replacing the entire coil set to prevent near-term repeat failures. Always verify shape and part references to ensure proper fitment for your specific model and engine.
