Detailed Description

SKP SKUF551 is a replacement ignition coil for select 2007-2019 Nissan and INFINITI vehicles, including the Nissan Armada, TITAN, Pathfinder, NV2500, NV3500, and INFINITI QX56 and QX80. It is designed for coil-on-plug systems and follows OE-style fitment requirements for straightforward service replacement. This part also cross-references 22448EZ00A for the same application.

As an ignition coil, this component converts battery voltage into the high voltage needed to fire the spark plug. When an original coil weakens or fails, the engine can develop rough idle, hesitation, hard starting, or reduced fuel economy. SKUF551 provides a replacement option for restoring ignition performance on the listed Nissan Armada, TITAN, and INFINITI QX56/QX80 platforms.

Common Issues This Part Addresses

• Engine misfire under load or at idle
• Hard starting or extended crank time
• Rough idle and hesitation during acceleration
• Check engine light related to ignition coil performance
• Loss of fuel efficiency caused by weak spark output

Installation Notes and Tips

Verify the vehicle’s engine configuration and coil-on-plug layout before ordering. Compare the original part number and connector style to confirm application match. Inspect spark plugs, boots, and wiring during service, since worn plugs or damaged connectors can affect coil performance.

For best results, install on a cool engine and follow the vehicle manufacturer’s service procedure for ignition system replacement. Clear diagnostic trouble codes after repair and confirm normal idle quality and acceleration.
