5 Best Spark Plugs For Hyundai Veloster Turbo

If you drive a Hyundai Veloster Turbo, keeping the ignition system in top shape directly affects how the car starts, runs and uses fuel. Choosing the right spark plugs helps you get more reliable starts, smoother throttle response and longer service intervals.

In this guide you’ll find options that balance performance, longevity and price so you can pick the plugs that best match how you drive and maintain your car.

Top Picks

How We Picked These Spark Plugs

You want spark plugs that fit your Veloster, last a long time and deliver reliable combustion under boost. We prioritized: fitment and compatibility with the 1.6L turbo, electrode material (iridium preferred for longevity and consistent spark), customer feedback and real-world reviews, price and value, and any performance or installation advantages (gapping out of the box, tapered/tiny electrodes for improved ignite). That approach helps you choose plugs that give better starts, smoother idle, improved throttle response and longer service intervals.

A-NAFTULY Iridium Spark Plugs (4 Pack)

These are a 4‑pack of fine‑wire iridium spark plugs designed for a range of 1.6L Hyundai/Kia engines. You’ll notice the thin 0.6 mm iridium tip and laser‑welded construction — that combo is aimed at better ignition consistency and longer life than a basic copper plug.

For everyday driving they help smooth idle and improve start‑up response; if you do occasional spirited driving or want a more reliable plug for highway runs, they hold up well. Do double‑check fitment for turbo models (this set is listed for naturally aspirated 1.6L Veloster/Accent and similar engines). They come pre‑gapped (0.036″) and include a 12‑month warranty, so you can swap them in without fuss and get back on the road quickly.

What People Say

Buyers say these plugs are easy to install, come pre‑gapped, and immediately improve smoothness and start‑up. A few customers also noticed better fuel economy after swapping them in.

Overall Sentiment: Positive

JDMON Coil Pack & Spark Plug (Fit 1.6L)

This is a combined ignition coil pack and iridium spark plug set that’s matched to a range of 1.6L Hyundai and Kia engines — including the Veloster and Accent lines for the model years listed. If you do your own maintenance, it’s the kind of kit that gets you back to smooth idling and reliable starts.

For everyday driving it helps keep ignition consistent; if you press the turbo a bit on weekend drives or spend long miles on the highway, the iridium electrodes and high‑temp coil materials are meant to hold up better than a basic plug. Installation does require some care (and alignment when reinstalling bolts can be fiddly), so plan for a bit of time or ask a tech to help. If you want an OE‑style replacement that focuses on stable spark and longevity, this one’s worth a look.

What People Say

Buyers report the parts improve how the car runs and start reliably; a couple of users noted the installation can be a bit tricky when lining up bolts.

Overall Sentiment: Positive

Ease Of Use

Durability

Built with high‑insulation coil materials and an iridium electrode on the spark plug; designed to resist heat and corrosion so the spark gap stays stable for longer than basic plugs.

• OE part number replacements for UF652 / C1803 / 273012B100

DENSO Iridium Power Spark Plugs (4-Pack)

These DENSO Iridium Power plugs are built around a tiny 0.4 mm iridium tip and a tapered, U‑groove ground electrode — that combo is meant to give a stronger, more focused spark than a standard plug. For everyday driving you’ll likely notice crisper starts and steady idling, plus a small bump in throttle response and fuel efficiency.

If you like to push the car on spirited weekend drives, the iridium tip and robust construction are aimed at handling higher temperatures and repeated load. Important: this listing is for the 1.6L Veloster fit (2012–2014) — if you have a Turbo model, double‑check fitment before you buy.

If the plug spec matches your engine, these are a practical OE‑style upgrade that leans performance without being fussy to install.

What People Say

Buyers note reliable fitment for listed Veloster years and praise the iridium tip and electrode design for smoother idle and modest fuel‑economy gains.

In day‑to‑day driving you’ll notice stable idling and consistent starts, and the iridium tip is intended to last much longer than a standard copper plug.

For occasional spirited runs the construction helps retain good spark under load, but double‑check fitment if you have a Turbo model — this listing targets the naturally aspirated 1.6L. If you want a no‑nonsense OE‑style swap that reduces the number of plug changes down the road, these are an easy, practical choice.

FAQ

How Do I Choose The Right Spark Plugs For My Hyundai Veloster Turbo?

You should start by checking your vehicle identification number (VIN) or the owner’s manual to confirm the exact engine variant and OEM part numbers before buying. For turbocharged Velosters you’ll typically want a high-quality iridium or fine-electrode plug because they offer longer life and more consistent spark under boost.

Match thread size, reach, and heat range to the factory spec and verify fitment against the OEM part number; many aftermarket options list compatible OEM numbers so you can cross-check. Also make sure the plugs are compatible with your ignition coils and that the gap is set to manufacturer specifications, since improper gap or heat range is a common cause of misfires and reduced longevity.

Can I Install Spark Plugs Myself And What Precautions Should I Take?

Yes, you can install them yourself if you have basic tools and follow safe procedures: work on a cool engine, use a proper spark-plug socket and extension, start threads by hand to avoid cross-threading, and tighten to the manufacturer torque spec (check your service manual). Many modern iridium plugs come pre-gapped, but you should verify the gap before installation. Avoid applying excessive anti-seize unless the manufacturer recommends it, and use dielectric grease on the inside of the boot if you want easier removal and to prevent moisture ingress.

Replace all plugs at the same time for consistent performance, and if you have a misfire or rough idle after installation, check coil health and wiring because a bad coil can ruin a new plug.

Will Upgrading To Iridium Spark Plugs Improve Performance And Fuel Economy?

Upgrading to quality iridium plugs can give you smoother idle, more reliable starts, and more consistent combustion, which may yield a small improvement in throttle response and fuel economy in everyday driving. You shouldn’t expect large horsepower gains from plugs alone; meaningful power increases require tuning and supporting modifications.

The real advantages are longevity and stable performance under boost, which is especially useful for turbo engines like the Veloster Turbo. Choose proven brands and correct specifications for the best real-world results.

Drivers Top Picks

When choosing between the A-NAFTULY Iridium 4-pack, the JDMON coil pack & spark plug combo, and the DENSO Iridium Power plugs, you typically prioritize longevity and ignition performance plus whether you need a matched coil-and-plug replacement or just plugs. You’ll also weigh OEM fit and proven reliability (DENSO), aftermarket value and performance (A-NAFTULY), and the convenience of a matched coil-pack option (JDMON), along with price and ease of installation.

Wrapping Up

Now that you’ve seen the options, pick based on what matters to you most. If you want proven reliability and OEM-style performance, the NGK Laser Iridium is an excellent choice. If you want a strong performance upgrade for less money, the DENSO Iridium Power and the A-NAFTULY iridium pack are both solid — A-NAFTULY especially if you’re watching cost.

If you’re replacing coils at the same time, consider the JDMON kit to cover both items. Whatever you choose, verify fitment for your model year and follow proper installation torque and gap specs so the plugs deliver the best results for your Veloster Turbo.
