Nilight Ignition Coil Pack Set of 4 (UF549) for Select Nissan/Infiniti Models (2004–2018)
Product description
What this ignition coil set is for
A failing ignition coil doesn’t always announce itself dramatically. More often, it shows up as rougher running, hesitation, worse fuel economy, or the dreaded check engine light. The Nilight Ignition Coil Pack Set of 4 is designed as an automotive replacement set for specific Nissan and Infiniti applications, using OE number matching to help you get the right interface.
On paper, the pitch is straightforward: replace aging factory coils with a set meant to help the engine run smoother again. And since ignition coils are a known wear item on many vehicles, having a reliable replacement method matters—especially when you’re trying to fix symptoms rather than guess at random.
Still, it’s not perfect for every situation. If your vehicle’s issue is caused by something else (fuel delivery, sensors, wiring, misfires unrelated to coils), coils may not be the whole answer. That’s the main limitation to keep in mind before buying.
Key takeaways before you buy
This set includes 4 ignition coils, intended to match a range of Nissan/Infiniti years and models listed in the product compatibility notes. The listing also emphasizes that you verify fitment using the vehicle details tool and the OE numbers.
The most purchase-relevant detail is the OE reference: UF549. The description also lists multiple OE numbers associated with the replacement part, so you’ll want to cross-check what your current coil assembly uses and make sure the quantity and interface type line up.
One more practical note: the kit is positioned as a replacement set for common model spans (including Sentra, Altima, Rogue Select, and others referenced), but the safest path is still confirmation by year/make/model plus OE matching. Fitment errors here are the easiest way to waste money.
What stands out in everyday use
The manufacturer claims several durability-focused materials. The wire coating is described as shock-resistant with a long service life. The silicone rubber boot is also highlighted for temperature tolerance (as low as -40°F and up to 302°F) to help with insulation.
They also mention installation support: the silicone rubber boot contains silicone oil, which should make replacement and installation easier.
In real terms, this is the kind of set you’d consider when you want the engine to idle smoother and feel more consistent during light driving—after a misfire trend starts, or after you notice hesitation and worsening mileage alongside a check engine light.
The parts that matter most: fitment and OE numbers
If you only do one thing before purchasing, do this: verify fitment using amazon’s Your Garage function (as suggested in the listing) and confirm the OE number of the replaceable ignition coil.
Why this matters: ignition coils can look similar across trims and years, but the interface type and quantity must match. The listing explicitly asks you to check the OE number, the ignition coils interface quantity, and the interface type before buying.
The listing references OE numbers including UF549, C1696, 5C1753, E1049, 52-2108, IC629, 22448ED000, 22448JA00A, 22448JA00C, COP292, C751, UF549X, GN10241, 1788369, IGC0002, 673028, 22448-ED000, 22448-1KT1A, among others. Use this as a cross-reference tool, not as permission to skip verification.
Who it suits (and who should skip it)
It’s a solid fit if you’re troubleshooting ignition-related symptoms—things like hesitant running, rougher operation, increased gas mileage, or a check engine light that points toward coil failure—and you can confirm your vehicle’s OE number matches UF549 (or one of the listed equivalents).
It may not be a great match if you don’t plan to verify fitment carefully, or if your root cause diagnosis is uncertain. Without OE confirmation, the chances of mismatch go up, and with ignition parts, mismatches are a fast way to end up back at square one.
Practical installation expectations
The listing calls out “easy installation” and suggests the silicone boot design and silicone oil content help during replacement. That’s helpful if you already handle basic auto maintenance or have a mechanic familiar with ignition coil swaps.
Micro-scenario: imagine you’ve got a Sentra or Altima with intermittent hesitation under acceleration and an illuminated check engine light. If your diagnostics (or the mechanic’s check) points to coil failure, replacing coils as a set of four can help restore consistent firing rather than swapping one component and hoping the rest behave.
Tech specs
- Type: Ignition coil pack set (replacement ignition coils)
- Function: Intended to restore smoother engine running when factory coils fail over time
- Quantity: Set of 4 ignition coils
- OE reference to verify: UF549
- Temperature tolerance claim for silicone rubber boot: -40°F to 302°F
Is it worth it?
Buy this Nilight ignition coil set if you’re seeing ignition-coil-type symptoms and you can verify compatibility using the year/make/model tool plus the OE number (UF549 or a listed equivalent). The durability-oriented material claims and the inclusion of silicone oil in the boot are the kind of details that can make the swap feel less frustrating and help with long-term insulation.
Skip it if you don’t want to do the fitment/OE matching step, or if your check engine light isn’t confirmed as coil-related. This isn’t the type of purchase you want to gamble on—especially since the listing itself stresses interface quantity and interface type verification.
