Marsram Ignition Coil Pack & Spark Plug Kit UF652 4‑Pack for Kia Rio/Soul 1.6L — Double‑Iridium OE Fit

Marsram UF652 ignition coil pack with four iridium spark plugs replaces factory coils and plugs for 1.6L naturally aspirated Kia and Hyundai engines, restoring reliable spark and responsive throttle.

This replacement kit pairs four Marsram UF652 ignition coils with four double-iridium spark plugs engineered for 1.6L naturally aspirated engines used in select Kia and Hyundai models from 2012–2019. The set is designed to match or exceed original equipment shape and performance, using epoxy-encapsulated housings and high-conductivity copper windings in the coils plus durable iridium electrodes in the plugs. Before ordering, confirm your engine is the 1.6L naturally aspirated variant—UF652 is shorter than UF651 and will not fit 1.8L, 2.0L, or turbo engines.

Which cars and engines will this Marsram kit fit?

This kit is built exclusively for naturally aspirated 1.6L L4 engines. Compatible Hyundai models include multiple Accent and Veloster trims from 2012–2017 (and select 2018–2019 trims). Compatible Kia models include Rio and Soul 1.6L trims from 2012–2019.

• Hyundai: Accent GLS/GS/SE/Sport/Value Edition (2012–2019 various trims), Veloster Base and RE:FLEX (2012–2017).
• Kia: Rio EX/LX/S/SX (2012–2019), Soul Base (2012–2019).
• Fits only naturally aspirated 1.6L engines; not compatible with turbo or larger displacement engines.

How do Marsram coils and plugs improve starting and throttle response?

The Marsram coils use high-conductivity copper windings and epoxy-sealed housings to maintain a strong, consistent spark under heat and vibration. The double-iridium spark plugs resist corrosion and minimize gap growth, helping maintain efficient combustion over time for quicker starts and steadier acceleration.

• Epoxy and high-strength plastic housings resist heat-related deformation.
• Copper coil cores increase ignition speed and reliability.
• Double iridium electrodes reduce spark gap wear for consistent combustion.
• Helps preserve factory-like performance and drivability.

Is installation straightforward and do these replace OE part numbers?

Yes—Marsram coils and plugs are produced to OE form, fit, and function standards for easy swap-in installation. The package includes four coils and four plugs and is backed by standard aftermarket testing; still verify part numbers and physical coil length before installation.

• Replaces UF652 and factory numbers such as 27301-2B100 and 273012B100.
• Spark plug equivalent: part 93815 with double iridium electrodes.
• Simple bolt-and-plug installation—no special tools beyond basic hand tools and torque wrench.
• Ships as a complete 4-coil + 4-plug kit for one bank or full 4-cylinder replacement.

What warranty and support come with the Marsram kit?

Marsram provides a one-year aftermarket warranty on this ignition coil and spark plug kit, plus customer support for fitment and troubleshooting. If you encounter issues, contact Marsram directly for assistance and warranty claims to resolve defects or compatibility concerns.

• One-year limited warranty covering manufacturing defects.
• Customer support for compatibility confirmation before purchase.
• Packaged as four coils and four plugs for full replacement of a 4-cylinder ignition bank.

Who this is for: Drivers who own a Kia Rio, Kia Soul, Hyundai Accent, or Hyundai Veloster with the 1.6L naturally aspirated engine and who want an OE-form replacement that restores spark reliability and maintains engine responsiveness. This kit suits DIY mechanics and professional technicians seeking a complete 4-cylinder ignition refresh; confirm engine size and coil length prior to ordering to ensure correct fit.
