Ignition Coil UF549 Pack of 4 Compatible with Nissan & Infiniti

In this review the focus is on the UF549 ignition coil pack set of 4 as a direct replacement for many Nissan and Infiniti models. The bottom line: this set is for owners who need a straightforward, cost-effective replacement that restores reliable spark and reduces misfires. The reviewer found the coils offer consistent output under stress and improved engine smoothness compared with worn units, making them a practical choice for routine repairs and preventive maintenance.

Key Features

• Wide vehicle compatibility: Works as a direct replacement on many Nissan and Infiniti models, reducing the time spent matching part numbers.
• High-grade copper windings: The internal copper wire improves conductivity to support stronger, more consistent ignition for smoother running.
• Engine performance stability: Tested under high-temperature and high-pressure cycles to stabilize output and reduce hesitation or misfire in daily driving.
• Reduced fuel waste: More efficient spark delivery can lead to lower fuel consumption compared with degraded coils.
• OEM part number cross-reference: Replaces common part numbers such as UF549 and GN10241 for easier fitment verification.

Who It's For

The UF549 pack is aimed at DIY mechanics and independent shops working on Nissan Altima, Sentra, Rogue, Frontier, Versa and compatible Infiniti models who want a reliable replacement without premium pricing. It is especially useful for owners experiencing misfires, rough idle, or reduced engine response who need a direct swap.

Those with vehicles outside the listed compatibility years or owners seeking brand-store OEM parts might prefer an original equipment coil. Also, if a vehicle has additional electrical faults beyond ignition coils, a full diagnostics approach should be used rather than only replacing coils.

Pros & Cons

Pros

• Good fit and compatibility with many Nissan and Infiniti years and models.
• Improved ignition stability under heat and stress thanks to quality copper windings.
• Easy installation noted by customers, with fewer reported misfires after swap.

Cons

• Not an OEM-branded coil so buyers who prefer factory-branded parts may look elsewhere.
• Long-term durability beyond initial use is not specified, so rigorous warranty claims should be checked before purchase.
