How We Picked These Spark Plugs
You want spark plugs that match your 2011 Kia Soul’s engine, deliver reliable ignition, and provide good value. We compared: fitment and OEM part compatibility (look for 97932, IZFR5L11, ZFR5FGP/UF-593 cross-references for 2.0L engines), electrode material (Iridium and Platinum for longer life, Copper for budget/OEM feel), durability and heat range for typical driving, kit completeness (coils + plugs when replacing both), customer feedback and ratings, ease of installation, and price.
You should pick iridium/platinum if you want longevity and slightly better performance; choose a kit when you replace a failed coil to avoid repeat work.
JDMON Ignition Coil & Spark Plugs Kit
If you’re working on a 2.0L Kia Soul, this kit gives you one ignition coil and four iridium spark plugs that are made to match OE part numbers like UF-593 and 2730123900. You get a coil built from high-insulation, heat-resistant materials and spark plugs with iridium electrodes for a steady spark and longer life. For everyday driving it helps keep starts smooth and idle steady; for longer trips or colder mornings that extra reliability matters. Installation does require some skill, so if you’re not confident under the hood, you might want a mechanic to do the swap — but if you enjoy a DIY job, it’s a straightforward way to refresh your ignition components.

If you want a simple OE-style replacement that’s familiar to most shops, these are a sensible choice.
What People Say
Buyers commonly note easier installs and an immediate improvement in drivability — fewer hesitations and smoother idling after swapping these in. Several reviewers also appreciated that the plugs came set to the expected gap.
Overall Sentiment: Positive
🗣️ Jason R. Albert
Ordered the plugs to go with a new set of coils since it’s best to change them both at the same time. We purchased for a 1.6L 2014 Kia Soul with 144k. There was a very bad stutter and hesitation. The plugs were already set to the right gap, so I didn’t need to worry about that. Comparing the new plugs to the old you can see a difference. Once we finished, the stutter and hesitation was gone. I highly recommend these plugs. Very fast shipping.
🗣️ Christine Richardson
Worked great no issues installing them either, immediate difference.
Problem Solving
These plugs are aimed at fixing common ignition symptoms like rough idle, hesitation under load and intermittent misfires by restoring a consistent spark. They’re a straightforward way to troubleshoot ignition-related drivability problems before moving on to coils or sensors.
Eco Friendliness
They’re copper-based, so they won’t last as long as iridium or platinum options, but choosing a durable, direct-fit replacement reduces waste from returns and mismatched parts. Replacing plugs on schedule helps engines run more efficiently, which is a small environmental plus.
Key Benefits
- Direct replacement fit for many Kia Soul 1.6L and 2.0L L4 model years
- Genuine Champion quality built to OE-fit standards
- Copper construction with durable materials for reliable spark delivery
- Often arrives pre-gapped to common specifications, saving setup time
- Pack of four covers a full 4-cylinder replacement

For weekend DIY jobs you’ll appreciate the direct-fit approach and OE-level feel; for a road-trip prep they can help reduce hesitation and make starts more predictable.

These work great in our Hyundai Elantra 2017. Car runs so much smoother with them.

Bought these plugs a couple weeks after I got plugs and coils. The first set of plugs that came with the coils burned up in 2 weeks. I hope I have better luck with this set. Working very well so far.
Problem Solving
These plugs are a practical first fix for ignition symptoms like rough idle, hesitation under acceleration and intermittent misfires. Replacing worn plugs often eliminates those issues or at least rules out the plugs before you replace coils or dig deeper.

FAQ
How Do I Choose The Best Spark Plug Type For My 2011 Kia Soul?
You should base your choice on material, fitment, and your driving needs. Iridium plugs give the longest life and the most consistent spark, making them a great choice if you want fewer replacements and steady performance.
Platinum is a good middle ground with solid life and reliability. Copper works fine if you want a budget-friendly OEM-style replacement, but it wears faster. Always check fitment against your vehicle (match OEM part numbers or the vehicle-specific listings) so the thread size and heat range are correct, and prefer plugs that come pre-gapped to factory specs.
Should I Replace Ignition Coils When I Change Spark Plugs?
You don’t always have to replace coils every time you change plugs, but you should inspect them closely. If you have misfires, persistent check engine lights, visible cracking on coil boots, corrosion on terminals, or you’re installing new plugs after a long time, it’s smart to replace the bad coil(s) or swap the full set for consistency.
Many aftermarket kits bundle coils and plugs from brands like JDMON, TAUTOY, and A-Premium so you can replace both together for a cleaner repair—replacing coils with plugs can prevent repeated diagnostics later.
What Practical Tips Should I Follow For Installation And Maintenance?
You should confirm the correct gap and that plugs are vehicle-specific before installation; many iridium and platinum plugs come pre-gapped but it’s worth a quick check. Use a torque wrench and follow the manufacturer’s torque spec rather than just hand-tightening to avoid thread damage. Avoid putting anti-seize on plated threads unless the manufacturer recommends it, and apply a small amount of dielectric grease inside the boot to help with removal and prevent moisture unless coil manufacturer advises otherwise.
Typical longevity varies by material—iridium lasts longest, platinum is mid-range, and copper wears fastest—so plan replacements accordingly and watch for symptoms like rough idle, reduced fuel economy, hard starting, and misfires as signals it’s time to check the plugs and coils.
Top Customer Picks
When choosing between the JDMON Ignition Coil & Spark Plugs Kit, the 97932 Iridium Spark Plugs 4-Pack, and the TAUTOY UF593 Coil Pack + 4 Iridium Plugs, you typically weigh compatibility with your 2011 Kia Soul, whether you need a full coil-and-plug replacement or just plugs, and the longevity and performance benefits of iridium tips. You also consider ease of installation, price versus long-term value, and warranty or support so you get reliable starts, smoother idling, and fewer misfires.
Wrapping Up
Pick iridium or platinum plugs if you want longer life, better throttle response and fewer service stops. If a coil has failed or is aging, choose a kit that includes coils and plugs so you fix the root cause in one go. For tight budgets, quality aftermarket iridium sets like the BDFHYK or SYKRSS packs give reliable performance at a low price.
Match the part numbers and fitment to your 2.0L engine before buying, and change plugs and coils together when possible to get the best results.
