KSU Ignition Coil Pack for Hyundai Kia 1.8L/2.0L (Single Coil) Direct-Fit, OE Replacements UF651 C1804

KSU ignition coil pack — a direct-fit replacement coil engineered to restore consistent spark for compatible 1.8L and 2.0L Hyundai and Kia engines (sold here as individual coils, four needed for a full set).

Designed for specific 2011–2020 Hyundai and Kia models, this KSU ignition coil uses high-grade materials to deliver reliable ignition performance for 1.8L and 2.0L four-cylinder engines. Each unit replaces OE part numbers like 27300-2E000, UF-651, and C1804, and is built to resist corrosion and wear. Installation is straightforward for anyone comfortable with basic engine work; replacing coils can help eliminate misfires and improve engine smoothness when the original coils are failing.

How do I install a KSU ignition coil safely?

Installation is a step-by-step process that requires simple hand tools and basic mechanical familiarity. Remove the fuel rail and the old coil bolts/connectors in order, fit the new coil until it snaps, torque bolts to spec, then reseat the fuel rail. Replace all coils as a set when possible to ensure balanced performance.

• Unbolt and carefully lift the fuel rail to access coils
• Disconnect connectors and remove coil bolts in numerical order
• Install each coil until it snaps into place, tighten bolts to 50 inch-pounds
• Reseat fuel rail and verify connector engagement before starting

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

KSU coils use high-grade copper (sourced materials) and robust rubber seals to withstand heat, vibration, and moisture. The design focuses on maintaining high electrical resistance and a strong spark while resisting corrosion and abrasion — improving combustion consistency without altering engine tuning.

• Imported-grade copper windings for reliable conductivity
• Durable rubber insulation to resist engine-bay conditions
• OE-matching electrical characteristics for direct-fit replacement
• Reduces coil-related misfires and premature spark plug wear

What warranty and support does KSU provide?

KSU offers a limited exchange process for product-quality issues within 12 months of installation, requiring simple documentation. Keep the installation date and a photo of the coil code to submit for verification if a replacement is needed.

• 12-month exchange for qualifying manufacturing defects
• Submit installation date and coil code photo to KSU support
• Customer support will validate and issue a replacement if eligible

Who is this for: This KSU ignition coil is suited to DIY mechanics, independent repair shops, and fleet owners who need an affordable, OE-equivalent coil for the specified Hyundai and Kia 1.8L/2.0L engines. Choose KSU when you want a corrosion-resistant, high-grade-cooper-wound replacement that installs with standard hand tools and restores stable ignition performance — particularly when multiple coils show wear or misfire codes appear.
