Nilight UF669 Ignition Coil Pack (1 Pack) for Select 1.4L Chevy Cruze, Sonic, Trax, Volt & More
Product description
If your car is running a little rough, getting lower fuel economy, or throwing a check engine light related to misfires, a failing ignition coil is often the kind of problem you can actually address without replacing half the engine. This Nilight ignition coil pack is sold as a 1-pack automotive replacement, intended for specific 1.4L applications from the early-to-late 2010s.
That said, it’s not the right part for every car—even within the same model line. Where this purchase can go right is fitment verification before you order. If you match the OE number and confirm the coil’s interface pin quantity/type, you’re setting yourself up for a smoother swap.
The essentials
This is an ignition coil replacement designed to restore more stable spark output. Over time, factory coils can degrade, and that’s when drivers often notice symptoms like hesitant running, poorer gas mileage, and a check engine light. In theory, replacing the coil can help the engine run smoother and avoid issues that cascade into spark plug strain.
Nilight positions these coils around application-specific design, low emissions, and high energy output. The company also highlights materials and wire used to support high-shock resistance and longer service life. Whether you’ll feel every “performance” claim depends on the condition of your original coil and the exact cause of your fault code, but as a replacement strategy, it fits the most common coil-failure story.
What to know before buying (fitment is everything)
Before purchasing, Nilight explicitly recommends using amazon’s “Your Garage” function to match your vehicle year/make/model—and then verifying fitment using the OE number of the replaceable part.
You’ll also want to check interface details like the ignition coil connector pin quantity and interface type. It’s a small step, but it can save you from buying something that looks similar yet doesn’t connect the way your engine expects.
Compatible with select 1.4L L4 applications mentioned for: Chevrolet Cruze (2011–2015), Cruze Limited (2016–2018), Sonic (2012–2020), Trax (2013–2021), Volt (2011–2015), Buick Encore (2013–2021), and Cadillac ELR (2014–2016). Compatible part numbers listed include UF669 (and variations), D521C, 55577898, 55579072, 25198623, plus additional numbers such as C1810 / C-1810 and others in the list.
Where it shines
This coil pack is built around the practical goals most drivers actually care about:
- Smoother running after a coil-related issue
- Potential help for increased gas mileage caused by misfires (or rough combustion)
- A replacement approach that aims to reduce spark plug overload and protect the engine
In day-to-day terms, the experience usually looks like this: you diagnose a misfire or a coil-related check engine light, remove the old coil, and install the new one. If the fault is truly coil-related and the fitment matches, the engine behavior often becomes noticeably steadier at idle and under light throttle.
Limitations to keep in mind
This is sold as a set of 1, not a full-coil replacement bundle. If your car has multiple cylinders with misfires—or if you suspect more than one coil is failing—you may need a different purchase approach (or additional diagnosis) rather than relying on a single coil.
Also, coil failure symptoms can overlap with other issues. A new ignition coil won’t fix problems caused by bad spark plugs, wiring/connectors, fuel delivery, or a sensor fault. So if you’re buying without checking a code or doing a basic inspection, you might be gambling.

Is it worth it?
A solid pick if you already identified a coil-related issue, and you’re willing to verify OE number plus the coil connector pin quantity/interface type before ordering. It’s especially worth considering when your goal is to replace one failing coil and restore smoother engine behavior without going the “replace everything” route.
It may not be the best match if you don’t confirm fitment (a near-match can still be wrong), or if you’re seeing misfires across multiple cylinders and expect a single coil to solve everything. It’s also not the right way to proceed if the root cause might be plugs, wiring, or another engine component—on those cars, a coil swap alone can feel like a dead end.

What symptoms can an ignition coil cause?
On the listing, typical signs include increased gas mileage issues, hesitant running, and a check engine light due to ignition coil failure over time.
Do I need to verify the OE number?
Yes—Nilight specifically asks you to verify fitment using the OE number of the replaceable part, and also to confirm interface pin quantity and type.
Is this sold as one coil or multiple?
This listing is “1 Pack” and includes a set of 1 ignition coil pack.
Which engines is it intended for?
The fitment details provided are for select 1.4L L4 vehicles across certain model years for Cruze, Cruze Limited, Sonic, Trax, Volt, Encore, and Cadillac ELR (as listed).
How do I make sure it’s the right connector?
Check the ignition coils interface pin quantity and interface type before buying, not just the model name on the car.
