ENA Ignition Coil & Spark Plug Wire Kit — 8 UF414 Coils with 8 Iridium Platinum Plugs for 2007–2017 GM V8

ENA replacement kit includes 8 round UF414 ignition coils, 8 iridium platinum spark plugs and 8 high‑insulation spark plug wires engineered to restore reliable spark delivery on compatible GM V8 engines.

If your Chevrolet, GMC or Cadillac V8 is showing misfires, rough idle, poor starting or reduced throttle response, worn coils, plugs or wires are a common cause. This complete ENA kit bundles the round UF414 coil packs with iridium‑tipped platinum spark plugs and silicone‑insulated wires to provide a direct, bolt‑on swap for many 2007–2017 GM V8 applications. Designed as a cost‑effective alternative to OE parts, the set ships with eight coils and matched ignition components so you replace the entire ignition bank at once.

How do I confirm this UF414 coil kit fits my vehicle?

Before ordering, visually verify your current coil packs are the round UF414 style—square UF413 coils are different and will not fit. Use your vehicle year, engine displacement and VIN match against the fitment list, or cross‑reference the OE part numbers provided with your existing parts.

• Check coil shape: must be round UF414 (not square UF413)
• Compare OE numbers: 12573190, 5C1555, IC534 among compatibles
• Supported engines: 4.8L, 5.3L, 6.0L and 6.2L V8 models from 2007–2017
• Use the Amazon Confirmed Fit or your VIN to double‑check compatibility

What performance and durability features come with the ENA components?

ENA coils deliver 12V ignition output with bolt‑on mounting for a straightforward replacement, while the iridium platinum spark plugs provide a fine center electrode for consistent spark and longer wear than standard copper plugs. The included wires use silicone insulation and fiberglass‑reinforced cores to resist heat and electrical interference under hood heat.

• Coils: 12V, bolt‑on mount, 4 terminals per pack for reliable fitment
• Spark plugs: iridium plated center electrode, 1.0" gap, 14mm thread diameter
• Wires: 8mm diameter, silicone insulation, fiberglass reinforced core
• Materials chosen to handle engine bay temperatures and modern ignition demands

How difficult is installation and what tools do I need?

Installation is intended to be plug‑and‑play for experienced DIYers and mechanics familiar with coil‑on‑plug engines. Basic hand tools remove engine covers and fasteners; the kit replaces coils, plugs and wires in sequence to avoid mix-ups. If you’re unsure, a professional installation is recommended to ensure correct torque and gap settings.

• Common tools: ratchet, 16mm socket for plugs, torque wrench, screwdrivers
• Remove one cylinder at a time to maintain firing order and wire routing
• Torque spark plugs to manufacturer spec and confirm coil connectors seat fully
• Replace full bank to prevent unequal wear and recurring issues
