A-NAFTULY Iridium Spark Plugs for Hyundai & Kia 4-Pack — 0.6mm Tip, Laser-Welded

A-NAFTULY Iridium Spark Plugs 4-pack are direct-fit replacement plugs engineered for Hyundai and Kia 1.6L L4 engines, built to deliver consistent ignition performance and long service life.

These iridium-tipped spark plugs are designed as OE-style replacements for many Hyundai Veloster, Accent, Elantra and Kia Rio/Soul models from the 2011–2019 model years with naturally aspirated 1.6L or 1.8L engines. With a fine 0.6mm iridium center electrode, laser-welded construction and an engineered 0.036" gap, the set aims to restore reliable starts, smoother idling and efficient combustion while matching common reference numbers such as 92873, LZKR6AIX, 93815 and SILZKR6B10E.

Will these spark plugs fit my vehicle?

They are intended for Hyundai and Kia models with compatible engine codes and years. Check the engine size and year against the listed fitment before ordering to ensure a direct replacement without modification.

• Compatible with Hyundai Accent (2012–2019) L4 1.6L
• Hyundai Veloster (2012–2017) L4 1.6L naturally aspirated
• Kia Rio and Soul (2012–2019) L4 1.6L
• Also referenced to Hyundai Elantra 2011 L4 1.8L where applicable

How do these iridium plugs affect fuel efficiency and drivability?

Their 0.6mm iridium fine-wire center electrode focuses the spark and promotes more complete combustion compared with larger electrodes. That improved ignition consistency can help the engine run smoother, reduce misfires and support steady fuel use under normal driving conditions.

• Fine-wire iridium tip concentrates spark energy for cleaner burns
• Laser-welded construction resists electrode wear over time
• Correct 0.036" gap optimizes spark distance for recommended engines
• May reduce rough idling and hesitation when installed correctly

What materials and build quality do these plugs use?

The center electrode uses an iridium alloy chosen for its high melting point and wear resistance, rated harder than platinum. Combined with a welded joint and durable insulator, the plugs are engineered for longevity in modern gasoline engines.

• 0.6mm iridium fine-wire center electrode for long life
• Laser-welded tip for secure electrical contact and durability
• Designed to withstand heat and electrical erosion in high-load conditions
• Manufactured to match common OEM reference numbers

What comes in the package and what support is offered?

You receive a set of four iridium spark plugs in one package—everything needed for a full four-cylinder replacement. The seller provides a 12-month limited warranty and customer support for fitment or quality questions.

Who is this for: drivers and DIY mechanics who own compatible Hyundai or Kia vehicles with naturally aspirated 1.6L (and some 1.8L) engines and want an OEM-style iridium upgrade for reliable ignition, longer plug life and improved combustion stability. These plugs suit routine maintenance, tune-ups, or anyone replacing worn spark plugs to restore engine smoothness and consistent starts. Always confirm fitment with your vehicle’s engine code and follow proper torque and installation practices; consult a professional if unsure.
