ENA 8-Pack Red Round Ignition Coil & Iridium Spark Plug Wire Kit — OEM-Fit, Plug-and-Play

ENA's 8-pack red round ignition coils paired with eight iridium platinum spark plugs and red silicone wires deliver a complete plug-and-play ignition kit for compatible GM V8 engines.

This all-in-one ENA kit replaces worn ignition coils, spark plugs, and wires on many Chevrolet, GMC, Cadillac and Pontiac V8 models. Built to match OEM mounting points and electrical specs, the set includes round UF414-style coils (confirm UF414 before ordering), precision-gapped iridium plugs, and red silicone-insulated spark plug wires for improved durability and a tidy engine-bay appearance.

How do I know this kit fits my vehicle?

Compatibility centers on the round UF414 coil style — not the square UF413. Use your vehicle year, make and engine size to verify fit, or check original coil part numbers against the listed references. Fitment covers many Chevy Silverado, Tahoe, Suburban, Avalanche, Camaro, Colorado, GMC Sierra, Yukon, and Cadillac Escalade and related Pontiac models with V8 engines from the mid-2000s to mid-2010s.

• Confirm your coil is ROUND (UF414) before ordering.
• Common compatible engines: 4.8L, 5.3L, 6.0L, 6.2L V8s across listed years.
• Reference numbers included: UF414, 1788407, IC534, 12573190, CUF414, etc.
• Use vehicle fit tool or compare part numbers for certainty.

What are the main technical features and materials?

The kit combines 8 bolt-on 12V round ignition coils, 8 iridium platinum-tipped spark plugs gapped to 1.0 in, and 8 red silicone-insulated wires with fiberglass-reinforced cores. Coil and plug dimensions follow OEM-style specifications for easy replacement and consistent electrical performance. Wires are sized and insulated to resist heat and abrasion while maintaining stable signal transfer.

• Coil: 4 terminals, bolt-on mount, engine-bay location, 12V rating.
• Spark plugs: iridium/platinum tip, 1.0" gap, 14 mm thread, 16 mm hex.
• Wires: 8 mm diameter, fiberglass-reinforced latex graphite core, red silicone insulation.
• Package: 8 coils, 8 plugs, 8 wires, 12-month warranty.

How easy is installation and what tools or prep are required?

ENA-designed coils and plugs use the same mounting and electrical connectors as many OEM parts for a straightforward swap — no custom wiring required. Basic hand tools (socket set, torque wrench, dielectric grease) and a clean workspace are all that’s typically needed. Follow factory torque specs for plug and coil bolts and confirm wire routing matches original harness clips to avoid contact with hot components.

• Plug torque and coil-bolt torque per factory spec recommended.
• Dielectric grease for boots helps seal and prevent misfires.
• Match wire lengths and routing to factory harness to prevent chafing.
• 12-month warranty and part references included for verification.

Why choose iridium spark plugs and a full coil-plus-wire kit?

Iridium-tipped spark plugs offer fine electrode durability and consistent spark performance over many miles, while replacing coils and wires together ensures a balanced ignition system. A full kit reduces troubleshooting — you replace all wear items at once to restore consistent firing and reduce the chance of intermittent misfires. The red wires also add a visible upgrade in engine appearance while meeting functional insulation needs.

• Iridium tips: long life and stable gaps.
• Complete kit: avoids mixed-age component mismatches.
• Red silicone wires: heat resistance plus visual upgrade.
• Plug-and-play design matched to OEM mounting and connectors.

Who is this for: This ENA 8-pack coil, plug and wire set is intended for DIY mechanics, independent shops, and fleet owners maintaining compatible GM V8 vehicles (verify round UF414 coils before ordering). It’s suited for anyone replacing aging ignition components who wants a single vendor solution with OEM-style fitment and a 12-month warranty.
