Marsram Ignition Coil Pack with 4 Double-Iridium Spark Plugs for Kia/Hyundai 1.6L UF652 Direct-Fit

Marsram Ignition Coil Pack UF652 with four double‑iridium spark plugs is a direct-fit replacement for naturally aspirated 1.6L Kia and Hyundai engines, restoring reliable ignition and smoother starts.

This kit combines four UF652 ignition coils and four double‑iridium spark plugs engineered for naturally aspirated 1.6L L4 engines used in select Kia and Hyundai models from 2012–2019. The coils use high-strength engineering plastic and epoxy resin exteriors and high-conductivity copper windings inside to withstand engine heat and deliver fast, consistent sparks. The included spark plugs feature advanced center electrodes and corrosion‑resistant materials designed to resist gap growth and provide efficient combustion over their service life.

Which models and engines will this UF652 kit fit?

The UF652 kit is intended exclusively for 1.6L naturally aspirated (non‑turbo) inline‑4 engines. It does not fit 1.8L, 2.0L or turbocharged applications. Always verify your factory coil dimensions—UF652 is shorter than UF651—before purchase.

• Kia: Soul Base 2012–2019, Rio LX/EX/S/SX 2012–2019 (1.6L L4 models).
• Hyundai: Accent and Veloster 1.6L naturally aspirated versions (selected years 2012–2017/2019).
• Replaces OEM numbers: 27301‑2B100, 273012B100 and aftermarket references like 5C1860, GN10634.

How do these ignition coils and spark plugs improve engine performance?

These coils and plugs are built to match or exceed OE design so they deliver dependable firing, quicker ignition response and more complete combustion when installed correctly. The copper coil core improves conductivity for a stronger spark, and the double‑iridium plugs maintain their gap and spark efficiency over time.

• Stronger, more consistent spark for improved throttle response and smoother idling.
• Double‑iridium electrodes reduce wear and limit gap growth for longer service life.
• Heat‑resistant coil housings help prevent premature failure in high‑temperature engine bays.

What should I check before ordering and how easy is installation?

Confirm your vehicle’s engine displacement and that the original coil is the shorter UF652 style rather than UF651. The kit is designed as a plug‑and‑play replacement—electrical connectors and mounting points match OE specifications, and installation typically requires basic hand tools and standard safety precautions.

• Verify 1.6L naturally aspirated engine and coil length (UF652).
• Package contains 4 coils and 4 spark plugs—replace all at once for balanced performance.
• Meets OE form, fit and function; recommended torque specs and anti‑seize practices should be followed.

Who is this for: This Marsram UF652 coil and spark plug kit suits DIY mechanics, independent shops and fleet owners who maintain Kia Rio, Soul and select Hyundai Accent or Veloster 1.6L naturally aspirated vehicles. It’s targeted at anyone seeking a cost‑effective, OE‑compatible ignition refresh—especially when symptoms point to worn coils or plugs, and when you need a reliable, heat‑resistant aftermarket solution backed by a one‑year warranty and manufacturer support.
