A-Premium Ignition Coil and Iridium Spark Plug Kit — Set of 4 for Hyundai & Kia 2.0L/2.4L, Direct-Fit OE Specs

A-Premium's set of 4 ignition coils paired with iridium spark plugs is a direct-fit replacement kit engineered to restore consistent ignition, smoother idling, and reliable starts for many Hyundai and Kia 4-cylinder models.

This kit combines four bolt-on ignition coils matched with four iridium-tipped spark plugs, built to the OE-style specifications listed below. The components are designed for easy installation on valve-cover-mounted coils and include the electrical and mechanical tolerances needed for a correct fit. Use this kit when replacing worn coils and plugs together for a comprehensive ignition refresh that helps maintain efficiency and drivability.

Which vehicles and engine types does this kit fit?

These coils and iridium plugs cover a range of Hyundai and Kia models equipped with 2.0L and 2.4L naturally aspirated inline-4 gasoline engines across mid-2010s to 2020 model years. Confirm compatibility using the listed reference numbers or by matching your original parts.

• Hyundai Santa Fe 2019–2020 L4 2.4L; Santa Fe Sport 2016–2018 L4 2.4L

• Reference numbers: 273002GGA0, C988, GN10730, UF-764, UF764

What are the key technical specifications and installation details?

The ignition coils use a 4-terminal blade connector and bolt-on mounting to the valve cover. Electrical resistances and mechanical dimensions match expected OEM tolerances to ensure reliable spark delivery and fitment.

• Coil terminal count: 4; terminal type: blade; mount type: bolt-on
• Mounting location: valve cover; installation torque: 15–20 N·m
• Primary resistance: 0.68 ±10% ohms; Secondary resistance: 10.3 ±10% kΩ
• Spark plug thread diameter: 12 mm; gap: 0.7–0.8 in (pre-gapped)

Why choose iridium spark plugs paired with these coils?

Iridium is a refined alloy used for the spark plug's central electrode that resists wear better than standard nickel tips. The smaller, harder iridium tip supports a concentrated spark and longer service life under normal driving conditions.

• Iridium central electrode for extended plug life—typically longer than conventional plugs
• Helps maintain a stable idle and consistent ignition timing
• Can improve throttle response and starting reliability compared with worn plugs
• Manufactured to match coil electrical characteristics for stable performance

What warranty and aftermarket assurances are included?

A-Premium backs this ignition coil and spark plug kit with a one-year unlimited-mileage guarantee to cover defects in materials and workmanship. The warranty encourages confidence when installing aftermarket ignition components.

• One-year unlimited-mileage guarantee from A-Premium
• Kit sold as a matched set of 4 coils and 4 iridium plugs for synchronized replacement
• Reference numbers listed to verify cross-compatibility with OEM parts

Who is this for: This A-Premium kit is aimed at DIY mechanics and independent shops replacing worn ignition components on compatible Hyundai and Kia 2.0L/2.4L engines. It’s ideal when you want an OE-style coil installation, longer-lasting spark plugs, and a single matched kit to restore ignition reliability and responsiveness without sourcing parts separately.
