ENA Ignition Coil Pack Set for GM V8 Engines — Set of 8 Black, OE-Style UF271/D581 Fit (4.8L 5.3L 6.0L)

ENA D581 ignition coil pack set of 8 delivers plug-and-play replacement coils engineered for GM V8 engines (4.8L, 5.3L, 6.0L) to restore consistent spark delivery and reliable engine performance.

If your V8-equipped Chevy, GMC, Cadillac or Hummer is showing misfires, rough idle, or reduced responsiveness, worn or failing ignition coils are a common cause. This ENA set includes eight black coil packs (UF271 / D581 compatible references) designed to match OE mounting and electrical connections for a straightforward swap. The kit is sold with a 12-month warranty and targets popular models from late-1990s through mid-2000s GM lineups.

Which vehicles and engines will these coils fit?

These coil packs are built for a broad range of GM V8s. They cover many model years and displacements, so you’ll likely find compatibility across light trucks, SUVs, vans, and performance sedans with 4.8L, 5.3L, 6.0L and larger V8 engines.

• Chevrolet: Avalanche, Silverado 1500, Express vans, Monte Carlo, SSR (various years 1999–2006)
• GMC: Sierra 1500, Savana vans, C4500/C5500/C7500 Kodiak/Topkick (various V8s)
• Cadillac & others: Escalade 5.3L/6.0L; Hummer H2 6.0L; Envoy models
• Engine types: compatible with common GM 4.8L, 5.3L, 6.0L, 6.6L and select 8.1L V8 engines

How easy is installation and what do I need?

ENA coil packs are made with OE-style electrical connectors and bolt-on mounting for a near-direct replacement. Most installations require basic hand tools and about 30–90 minutes depending on engine layout and experience.

• Plug-and-play electrical connectors match factory harnesses
• Bolt-on mounting; retains factory fasteners or uses supplied hardware
• Recommended tools: ratchet, socket set, dielectric grease for terminals
• Replace spark plugs if original plugs are worn to avoid premature coil stress

What are the technical specs and part references?

The set contains eight individual coils rated for 12V operation with four terminals per pack where applicable; they are engineered to provide consistent spark output designed for GM ignition systems. Multiple OE cross-reference numbers help confirm fitment.

• Package: set of 8 black coil packs with bolt-on mount type
• Voltage spec: 12V; Terminal quantity: 4 where applicable
• Cross-references: UF271, D581, part numbers like 12558693, 12570553 and others
• Warranty: 12-month limited coverage included

Will replacing all eight coils improve drivability?

Replacing every coil at once eliminates weak links that cause intermittent misfires and inconsistent engine response. Even if only a few coils are faulty now, installing a full set provides uniform performance and can prevent future disruptions.

• Restores even spark delivery across all cylinders
• Reduces misfires, rough idle, and hesitation under load
• Helps ensure longevity when paired with fresh spark plugs
• Cost-effective compared to staggered replacements over time

Who is this for? This ENA coil pack set of eight is aimed at owners and technicians working on GM V8-powered trucks, SUVs, vans and performance cars from the late 1990s through the 2000s who need a reliable, direct-fit replacement. If you prioritize OEM-style fitment, broad model compatibility, and a straightforward installation with a one-year warranty, this kit is a practical choice.
