SYKRSS Ignition Coil Pack and 4 Iridium Spark Plug Kit — 4-Coil/4-Plug Direct-Fit for Hyundai, Kia & Genesis, Improved Durability

This SYKRSS kit includes four direct-fit ignition coils and four iridium spark plugs engineered for 2.0L and 2.4L turbo/NA four-cylinders and 5.0L V8 applications found in select Hyundai, Kia and Genesis models. Each component arrives ready to install—no wiring, modifications, or adapters required—and is built with upgraded internal materials for longer thermal and vibration resistance than many stock replacements.

Which vehicles and engines will this kit fit?

The kit is made for a range of Hyundai, Kia and Genesis vehicles that use the listed coil and plug part numbers. It covers Sonata, Santa Fe, Tucson, Santa Fe Sport, Optima, Sorento, Sportage, Stinger and Genesis G70/G80/G90 within the specified model years and engine sizes. Always confirm fitment with your VIN or year/make/model before installation.

• Hyundai: Sonata (2015–2019) 2.0L/2.4L, Santa Fe (2019–2020) 2.0L/2.4L, Tucson (2018–2020) 2.4L, Santa Fe Sport (2017–2018) 2.4L
• Kia: Optima (2016–2020) 2.0L/2.4L, Sorento (2016–2020) 2.0L/2.4L, Sportage (2017–2020) 2.0L/2.4L, Stinger (2018–2020) 2.0L
• Genesis: G70 (2019–2020) 2.0L, G80/G90 (2017–2019) 5.0L

How do these coils and plugs differ from stock replacements?

SYKRSS coils are precision-molded to OEM dimensions but use enhanced materials for durability and performance under extreme conditions. Coils include German enameled copper windings and Japanese epoxy potting, while the spark plugs use a fine iridium electrode and high-grade ceramic insulator for stable combustion over long life.

• Coils: upgraded wire and epoxy for vibration and heat resistance
• Boots: high-temperature silicone rated to 105°C continuous (125°C peak)
• Plugs: ultra-fine iridium tip and isostatic ceramic to reduce fouling
• Direct-fit: replaces UF764, 27300-2GGA0, 273002GGA0 and plugs like 93175

What performance changes should I expect after installation?

Replacing failing coils and worn plugs typically reduces misfires, smooths idle, and improves throttle response—especially when all units are replaced together. While results vary by vehicle condition, many owners notice a quicker startup, fewer check-engine alerts tied to ignition faults, and steadier high-speed cruising.

• Reduced misfire counts and related diagnostic codes
• Smoother idle and less hesitation under load
• More consistent power delivery and quieter operation
• Longer service interval thanks to iridium plug longevity

What support and warranty does SYKRSS provide?

SYKRSS backs this ignition kit with a one-year replacement promise to remove the risk of online parts buying. The team also offers fitment verification—send VIN or vehicle details and expect a reply within 12 hours on average—so you can confirm compatibility before you install.

• 1-Year no-questions replacement on failed coils or plugs
• Pre-install fitment check using VIN or Year/Make/Model
• Over 2,000 verified vehicle builds in the fitment database

Who is this for: This SYKRSS 4-coil + 4-plug kit is aimed at DIY mechanics and professional technicians who need a reliable, direct-replacement ignition set for specific Hyundai, Kia and Genesis engines. It’s particularly useful if you’re troubleshooting misfires, rough idle or ignition-related check-engine lights and prefer a drop-in solution with enhanced materials and a generous replacement policy.
