How does this coil pack match my vehicle’s original part?

The ENA coil pack is manufactured to meet the electrical and mechanical specifications of the original equipment it replaces. It lists cross-reference numbers used by technicians and parts suppliers so you can confirm compatibility quickly.

• Replaces UF510, 5C1482, 1788335, C1483 and other OEM references.
• Designed for the 5.6L V8 ignition layout used in listed Nissan/Infiniti models.
• Direct-fit housing and connector style for plug-and-play installation.

Will installing this coil pack fix misfires and rough idle?

A faulty coil pack is a common cause of ignition misfires, rough idling, and reduced engine responsiveness. Replacing a degraded unit with a correctly matched ENA coil pack can restore consistent spark timing, which often resolves intermittent misfire symptoms if ignition was the root cause.

• Improves spark consistency across all cylinders served by the pack.
• Reduces chance of check-engine light triggered by ignition misfires.
• Recommended to pair with fresh spark plugs for best results.

How difficult is installation and what should I prepare?

Installation is typically straightforward for anyone comfortable with basic engine bay work. The coil pack uses the vehicle’s original mounting points and electrical connector; you’ll need common hand tools and a clean workspace to complete the swap safely.

• Turn off battery before starting to avoid electrical shorts.
• Remove engine cover if present, unplug connector, unbolt old coil pack, and swap in ENA unit.
• Torque mounting fasteners to manufacturer specs and clear any diagnostic codes after installation.

What warranty and fit guidance does ENA provide?

ENA backs this coil pack with a 1-year limited warranty against manufacturing defects. Because multiple years and engine variants exist, the most reliable way to verify fit is using the vehicle-fit tool on the retailer’s page or by checking cross-reference part numbers against your vehicle’s service manual.

• 1-year limited warranty included with each purchase.
• Use the Amazon Confirmed Fit or enter your VIN to confirm compatibility.
• Keep original purchase receipt and part number for warranty claims.

Who is this for: This ENA ignition coil pack is aimed at DIY mechanics, independent repair shops, and owners of Infiniti QX56, Nissan Armada or Titan vehicles with the 5.6L V8 who need a reliable replacement for a failing coil pack. It’s suitable when you want an affordable direct-fit alternative to dealer parts, provided you confirm compatibility with your exact model year and engine configuration before ordering.
