KacuYelin UF652 Ignition Coil Pack & Iridium Spark Plug Kit — 4-Coil/4-Plug for Hyundai/Kia 1.6L (2012–2019), OE Fit

KacuYelin UF652 coil pack set with iridium spark plugs replaces worn ignition components on 1.6L Hyundai and Kia engines to restore reliable spark and consistent idle.

This kit combines four UF652 ignition coils and four iridium spark plugs engineered for non-turbo 1.6L L4 engines found in select Hyundai Accent, Veloster and Kia Rio and Soul models from 2012–2019. Each coil is built with high-conductivity wire and corrosion-resistant materials to deliver steady high-voltage output, while the iridium plugs use a laser-welded center electrode and high-alumina ceramic for improved heat transfer and long service life. The set matches OE fitment numbers and is produced in TS16949-standard facilities.

Which vehicles and engines will this UF652 kit fit?

This kit is specifically for naturally aspirated 1.6L L4 engines. It fits many Hyundai and Kia models produced in the listed years but will not fit turbocharged variants or other engine sizes.

• Compatible models: Hyundai Accent (2012–2017, 2019), Veloster (2012–2016); Kia Rio and Soul (2012–2019) with 1.6L engines.
• Not compatible with Turbo/T models or 1.8L/2.0L engines (these use UF651 or different parts).
• Always compare your existing coil appearance and engine displacement before ordering.

How do these coils and plugs improve engine performance?

Replacing degraded coils and plugs restores correct ignition timing and spark strength, which helps eliminate misfires, rough starts, and uneven idling. The improved spark stability can also support better combustion efficiency.

• UF652 coils use corrosion-resistant alloy and high-conductivity copper windings for steady high-voltage delivery.
• Iridium plugs feature a 360° laser-welded center electrode for consistent arc and durability.
• Proper ignition reduces fuel waste and can help improve drivability under load and at idle.

What are the build and quality features of the KacuYelin parts?

KacuYelin manufactures these parts in TS16949-standard facilities and validates them to meet OE specifications. Materials and assembly methods focus on longevity and reliable electrical output.

• Coils: imported copper wire, alloy steel components, oxidation-resistant finishes, and OE-equivalent connectors and part numbers (e.g., UF652, 27301-2B100).
• Plugs: high-alumina (≈95%) ceramic insulator, nickel-rich shell for heat transfer, and iridium center electrode with cold extrusion and laser welding.
• Each unit is factory-tested for consistent high-voltage performance before shipping.

How should I confirm fitment and install this coil and spark plug set?

Fitment is determined by engine displacement and coil appearance. Cross-check part numbers, then follow standard safety and torque specs during installation or have a professional mechanic fit them.

• Verify your vehicle’s engine is 1.6L L4 and not a turbocharged variant.
• Match the UF652 coil shape and connector to your existing coils; compare manufacturer OE numbers if available.
• Use correct spark plug gap and torque settings; replace coils and plugs in matched sets for balanced performance.

Who this is for: This KacuYelin UF652 coil pack and iridium spark plug set is aimed at owners and technicians of Hyundai Accent, Veloster, Kia Rio and Soul vehicles with naturally aspirated 1.6L engines who need OE-quality replacement ignition components. It suits do-it-yourselfers who can verify fitment and follow installation procedures, and service shops that prefer a tested, production-line replacement that aligns with OEM specifications.
