A-Premium Iridium Platinum Spark Plugs Pack of 4 for 1.6L L4 Hyundai & Kia — Fine Wire, OEM Fit

A-Premium Iridium Platinum spark plugs (pack of 4) are high-performance fine-wire electrodes built to deliver reliable ignition for 1.6L L4 Hyundai and Kia engines.

These four spark plugs combine an iridium-tipped center electrode with a platinum core to balance sharp ignitability and long service life. They match the OEM-style fitment and thread dimensions used on many Hyundai Elantra, Kona, Sonata, Tucson and select Kia Forte, Optima and Soul models with the 1.6L L4 engine. Each plug is assembled to meet resistance and gap specifications for smooth starting, efficient combustion and consistent throttle response.

Which vehicles and model years are these spark plugs compatible with?

These A-Premium plugs are designed to replace OEM part numbers like 97080 and SILZKR8E8G and suit a range of 1.6L L4 applications across Hyundai and Kia lineups. Always cross-check your owner’s manual or existing plug to confirm match before purchasing.

• Hyundai Elantra: 2017–2020 (1.6L L4)
• Elantra GT: 2018–2020; Kona: 2018–2020 (1.6L L4)
• Sonata: 2015–2019; Tucson: 2016–2018; Veloster: select years 2015–2020 (1.6L L4)
• Kia Forte/Forte5/Forte Koup/Optima/Soul: selected 2016–2020 1.6L L4 models

What are the key technical specifications and why do they matter?

These plugs use a fine iridium tip with a platinum core to reduce required firing voltage and resist electrode wear. Dimension and resistance details are matched to OEM expectations for easy installation and consistent spark timing.

• Center electrode tip: Iridium for sharper spark and durability
• Center core: Platinum to improve longevity and wear resistance
• Resistance: 5000 ohms to meet ignition system damping needs
• Gap: 0.031 in; Hex size: 5/8 in; Thread diameter: 12.00 mm; Reach: 26.5 mm
• Insulator height: 51.00 mm — matches OEM seating depth

How will these plugs affect daily driving and maintenance intervals?

Expect dependable starts, steady idling and predictable throttle response when plugs are installed to specification. The iridium/platinum combination extends service life compared with conventional plugs, reducing replacement frequency when properly gapped and torqued.

• Improved ignitability helps smoother cold starts and light-throttle acceleration
• Fine-wire tip reduces misfire risk under moderate load
• Recommended replacement interval: roughly 80,000–100,000 miles under normal driving
• Use specified gap (0.031 in) and correct torque for best longevity

Are these spark plugs easy to install and are they OEM-compatible?

Yes — the plugs are manufactured to OEM-like dimensions and thread specifications for straightforward swap-in replacement. They work with standard 5/8-inch sockets and follow the same reach and insulator measurements as factory parts.

• Direct-fit thread diameter (12.00 mm) and reach (26.5 mm) for compatible engines
• Use a 5/8-inch hex socket and proper torque to avoid damage
• Pre-gapped to 0.031 in; verify gap before installation
• Suitable for professional mechanics and experienced DIYers

Who is this for: Drivers and mechanics seeking a cost-effective OEM-style replacement for 1.6L L4 Hyundai and Kia engines who want the durability of an iridium-platinum electrode without changing ignition components. Ideal for routine maintenance, long-interval service plans, or restoring smooth operation after misfires or wear. Always confirm compatibility with your vehicle’s VIN and consult a repair guide for torque specs and installation procedures.
