What It Is / How It Works

This set of four dual iridium spark plugs is a replacement ignition component for compatible Hyundai and Kia models. Each plug uses dual iridium electrodes and a flat mounting base, and the set replaces OEM part numbers 18846-10060 and SILZKR6B10E.

Who It's For / Use Cases

Spark plugs suit Hyundai owners driving models such as the i30, ix35, ix40, or Accent, and Kia drivers with models such as the Rio, Soul, or Sportage, who need a direct fit ignition replacement. They also suit DIY mechanics handling their own engine maintenance and anyone noticing rough idling, poor acceleration, or decreased fuel efficiency in a compatible vehicle.

How to Use / Care

1. Installing a fresh set of spark plugs can restore lost power and smooth out a rough idle.
2. This set uses dual iridium electrodes, which are much harder and more durable.
3. These plugs are compatible with Kia Soul models that use the OEM part number 18846-10060 or SILZKR6B10E.
4. Confirm your vehicle uses the 18846-10060 or SILZKR6B10E part number before ordering.

How to Choose

Check your owner's manual or the part number on your current plugs to confirm the 18846-10060 or SILZKR6B10E number matches. Choose a set size that covers all cylinders, and consider dual iridium construction when you want a longer service life than standard copper plugs.

Frequently Asked Questions

How often should I replace these iridium spark plugs?
Iridium spark plugs generally last much longer than standard copper plugs, often up to 60,000 to 80,000 miles. Follow your vehicle manufacturer's recommended maintenance schedule.

Do I need to gap these spark plugs before installation?
Many iridium spark plugs come pre-gapped from the manufacturer. Check the gap with a tool and adjust it to your vehicle's specifications if needed, but avoid bending the iridium electrode.

What is the difference between single iridium and dual iridium plugs?
Dual iridium plugs have iridium on both the center electrode and the ground electrode. This design provides a more durable spark and can offer a longer lifespan than single iridium plugs, which only have iridium on the center electrode.

Can I use these spark plugs in a Hyundai Accent?
These plugs are compatible with the Hyundai Accent. Verify that your specific engine model requires the 18846-10060 or SILZKR6B10E part number for a proper fit.
