In this review the reviewer looks at the UF549 ignition coil pack set of 4 as a straightforward replacement option for many Nissan and Infiniti engines. The bottom line: this kit is for owners and mechanics who need a direct-fit, budget-friendly coil pack that restores ignition function quickly. Our review found the coils to be easy to install and compatible across a long list of models, making them a practical choice when a worn coil is suspected, though some users reported mixed longevity.

Key Features

• Quality Control: Produced in TS16949 certified facilities with 100% function and leakage testing for consistent initial reliability.

Who It's For

This set is best for DIY mechanics and independent technicians who need a cost-effective replacement that fits without adaptation. It suits owners of 2007-2019 Altima, Sentra, Rogue, Versa, NV200, NP300 and compatible Infiniti V6/V8 models looking for a coil that plugs in like the original.

Customers seeking the absolute longest-lasting, premium OE-branded coil or those who require dealer-backed parts coverage may prefer OEM units from the vehicle maker. Also, if a vehicle has recurring misfires after replacement, professional diagnosis of wiring, PCM and fuel system components is recommended before assuming the coils are at fault.
