SYKRSS Set of 4 Ignition Coil Pack UF247 + Iridium Spark Plugs 4503 (4-Pack) for Select 1.8L Chevy/Toyota Applications
Product description
If your check engine light is tied to ignition misfire symptoms, you usually want two things fast: the right parts for your specific engine and a set that’s built to handle heat without drama. This SYKRSS set bundles four ignition coil packs (UF247) and four spark plugs (4503) as a direct replacement approach, so you’re not piecing together mismatched components.
That said, the listing’s compatibility guidance is very much “confirm before you buy.” On paper, it lines up with several 1.8L models from the early 2000s onward, but you’ll still want to verify the coil OE number and the spark plug OE number match what your vehicle needs.
Key features to know before buying
This kit is designed around the idea of restoring spark consistency. The manufacturer states it meets or exceeds OE specifications for form, fit, and function, and it uses heat-resistant materials intended to withstand ignition-system stress.
They also position the coils and plugs as a replacement to help with common ignition-related issues like misfiring, rough idling, stalling, jerking/engine shake, poor fuel economy, clogged spark plugs symptoms, and check engine light illumination.
One practical detail: the package is built for fast installation with a “direct replacement” style setup, and it includes a manual in the box. That matters if you prefer doing the job yourself rather than waiting for a shop appointment.
Compatibility: where it fits (and where you should double-check)
The set is described as compatible with these applications (as listed):
- Chevy Prizm 1.8L L4 (2000–2002)
- Toyota Celica 1.8L L4 (2000–2005)
- Toyota MR2 Spyder 1.8L L4 (2000–2005)
- Toyota Corolla 1.8L L4 (2000–2008)
- Toyota Matrix 1.8L L4 (2003–2008)
- Pontiac Vibe 1.8L L4 (2003–2008)
If you’re in that window, it can be a straightforward way to refresh an older ignition system. But here’s the limitation: vehicle years can be messy, and coil/plug variants exist. The listing explicitly asks you to confirm compatibility by matching OE numbers for both the ignition coil (UF247 and related numbers) and the spark plug (4503), plus to check the pictures/item details.
What you’ll notice after install
On a typical install, replacing a matched set of coils and plugs can smooth out how the engine starts and idles. If your old plugs were fouling or your ignition coils were showing weakness under load, this is the kind of refresh that may reduce misfire feel (hesitation, shuddering) and help the engine run more evenly.
It’s not perfect, though—if your misfire is caused by something outside the ignition parts (like a sensor issue, vacuum leak, fuel delivery problem, or wiring), the new set may not fully solve the underlying cause. Still, for ignition-system symptoms, having a fresh four-coil/four-plug set is a sensible first “parts-side” step.
Technical overview (the essentials from the listing)
This kit includes ignition coil packs and spark plugs intended to operate reliably across engine speeds. The manufacturer mentions strict quality testing and stable high-voltage output under operating conditions.
Here are the concrete identifiers provided in the listing: - Ignition coil pack: UF247 (with multiple referenced OE numbers to cross-check) - Spark plug: 4503 - Package: ignition coil x4 and spark plug x4, plus a manual x1
Who it’s for—and who should skip it
It suits you if you:
- Drive a compatible 1.8L application listed above and you’re matching the OE numbers (UF247 for the coil, 4503 for the plug)
- Want a complete set (four coils + four plugs) rather than replacing just one component
- Prefer a direct-replacement style job to address misfire, rough idle, stalling, or check engine light symptoms that point toward ignition
You may want to skip it if you:
- Haven’t confirmed the coil OE number and spark plug OE number for your specific vehicle
- Think the problem might be primarily electrical, sensor, fuel, or airflow related (in that case, replacing ignition parts alone might not fix the root cause)
- Need a guaranteed fit without cross-checking—because the listing explicitly says to confirm compatibility using OE numbers and the vehicle year/make/model
Is it worth it?
Worth considering if your symptoms match ignition misfire behavior and you can verify UF247 coils and 4503 plugs are the right replacements for your exact setup. The “set” approach is convenient because it refreshes the ignition system as a matched group, and the installation is positioned as quick with a direct fit.
It’s not the best move if you’re buying based only on model/year and ignoring OE cross-checking—this is the kind of part where small differences can matter. If you take the time to confirm the OE numbers the listing calls out, this kit looks like a reasonable DIY replacement path for the specified vehicles.
Mini FAQ
Does this set replace both the ignition coils and spark plugs?
Yes. The kit is listed as including ignition coil x4 and spark plug x4.
What vehicles is it compatible with?
The listing names several 1.8L L4 applications, including Chevy Prizm (2000–2002), Toyota Celica (2000–2005), MR2 Spyder (2000–2005), Corolla (2000–2008), Matrix (2003–2008), and Pontiac Vibe (2003–2008). Still, you should confirm using the OE numbers.
How can I confirm compatibility before ordering?
Match your coil OE number to UF247 (and the referenced coil numbers in the listing) and your spark plug OE number to 4503. The listing also recommends checking the pictures/item detail page.
Will new coils and plugs fix a check engine light?
The listing claims these parts are intended to help with ignition-related faults and check engine light illumination tied to misfire-style issues. But if the cause is elsewhere, you may need additional diagnosis.
Is the install difficult?
The listing describes installation as fast and easy with a direct replacement design, and it includes a manual. Exact difficulty depends on your vehicle and experience level.
