KSU Ignition Coil Pack for Hyundai & Kia 1.8L/2.0L (4-Pack) — Direct-Fit, Copper Windings

KSU ignition coil pack (4-pack) replaces UF651/273002E000/C1804 for select Hyundai and Kia 1.8L and 2.0L engines, restoring reliable spark and smoother running.

This KSU replacement ignition coil is engineered as a direct-fit option for many Hyundai and Kia vehicles from 2011–2020 with 1.8L and 2.0L four-cylinder engines. Built with high-grade copper windings and durable insulation, it aims to deliver consistent spark energy, resist corrosion and abrasion, and prolong spark plug life. The kit ships as single new coils (package quantity listed per product) and is compatible with several OEM part numbers—check fitment carefully because some model years and engine variants use different coil types.

Which vehicles and engines will this KSU coil fit?

These coils are made for specific Hyundai and Kia models equipped with 1.8L or 2.0L inline-four engines. Fitment covers many model years, but there are known variations in some lineups—verify the connector and mounting style before purchasing.

How difficult is installation and what steps are involved?

Installation is straightforward for anyone comfortable working under the hood and using basic hand tools. Follow a consistent sequence when removing fuel rail and coils, tighten bolts to specified torque, and replace all coils as a set to avoid uneven performance.

• Remove fuel rail by unbolting two top bolts and lifting gently.
• Disconnect coil connectors and unbolt coils in order, then remove each coil.
• Snap new coils into place; tighten coil bolts to 50 in·lb (inch-pounds).
• Reinstall fuel rail, secure bolts, and verify connections before starting engine.

What are the construction features and benefits of the KSU coil?

KSU uses high-quality materials such as imported copper wire and durable rubber seals to improve electrical resistance and longevity. The design helps maintain strong spark delivery and resists environmental wear that can cause coil failure.

• High-grade copper windings (ELEKTRISOLA) for consistent conductivity.
• Robust insulation and seals to resist corrosion and abrasion.
• Designed to reduce plug overload and extend plug and engine service life.
• Backed by a 12-month exchange policy for manufacturing issues (follow store procedure).

Who this is for: The KSU ignition coil is intended for DIYers and professional technicians replacing worn or failing coils on compatible Hyundai and Kia 1.8L/2.0L engines who want a cost-effective direct-fit alternative to OEM parts. Confirm your vehicle’s engine code and coil type before ordering to ensure compatibility. If you prefer preventative maintenance, replace all coils at once to maintain balanced performance and avoid repeated labor.
