ENA Round Ignition Coil Pack UF414 for GM 5.3L V8 — Valve-Cover Bolt-On, 12V Single Coil

ENA Round Ignition Coil Pack UF414 is a direct-fit replacement single coil designed to restore reliable spark delivery for many GM V8 engines (4.8L–7.0L), including Silverado, Sierra, Tahoe, Yukon, Suburban, Corvette and related models.

If your engine is misfiring, running rough at idle, or the check engine light is on with an ignition-related code, installing the correct coil can often resolve the issue quickly. This ENA coil is the ROUND style (UF414) — not the square UF413 — and is built as a bolt-on valve-cover-mounted unit with a 12V electrical rating. It ships as a single coil pack and includes a 12-month warranty.

How will this coil fit my vehicle and which models does it cover?

This coil is manufactured to match OE-style round ignition coils used across many GM V8 applications. It lists broad fitment across Chevrolet, GMC, Cadillac, Pontiac and Hummer models with 4.8L, 5.3L, 6.0L, 6.2L and select 7.0L engines.

• Common fits: Chevy Silverado/Sierra 1500 (2007–2013), Suburban/Tahoe (2007–2014), Corvette (2006–2013), Camaro (2010–2015).
• Also fits: Avalanche, Colorado, Impala, Monte Carlo, Express, Savana, Yukon, Escalade, H2/H3, G8, GTO and more as listed in the detailed fitment.
• Verify part numbers (UF414, C1512, D514A, 12699382, etc.) and confirm your existing coil is the round style before purchase.

What are the technical details and installation basics?

The ENA UF414 is a bolt-on coil that mounts to the valve cover and uses four electrical terminals. It’s designed for plug-and-play replacement: unplug the old connector, unbolt the coil, and swap in the new unit using original fasteners.

• Terminal quantity: 4; Voltage: 12V.
• Mount type: bolt-on; mounting location: valve cover.
• Sold as a single coil pack — install per cylinder as needed; torque fasteners to OEM specs.

Will this coil improve engine performance or fix misfires?

Replacing a failing ignition coil with a correct-fit unit often restores proper combustion timing and smoothes out misfires caused by weak or intermittent spark. It addresses ignition-related drivability symptoms when a coil is the underlying cause.

• Helps eliminate rough idle and cylinder misfire codes if coil failure is present.
• Restores spark consistency comparable to OE specifications for compatible engines.
• Not a solution for fuel, compression, or sensor issues — diagnose codes first.

Who is this for: This ENA UF414 round ignition coil is aimed at DIY mechanics and professional technicians who need a cost-effective, OEM-style replacement for one faulty ignition coil on GM V8 vehicles. It’s ideal for owners of Silverado, Sierra, Tahoe, Yukon, Suburban, Corvette and other compatible models who have verified fitment and identified a coil-related code or symptom. Before ordering, confirm the round coil design on your engine and cross-reference the supplied part numbers. The unit ships as a single coil pack and comes with a 12-month warranty from ENA.
