NPAUTO ignition coil pack and spark plug kit is a direct-fit, four-piece replacement for turbocharged 1.6L L4 engines used in many Hyundai and Kia models from 2015–2020, restoring reliable ignition performance.

This kit combines four pre-gapped spark plugs with four high-quality ignition coils manufactured to meet or exceed OEM tolerances. It is built as a direct-replacement assembly (interchange UF817 / UF-817 / 273012B120) for affected turbocharged 1.6-liter four-cylinder engines. Whether you’re troubleshooting misfires or refreshing routine maintenance components, the set is supplied ready-to-install to save time and reduce parts-matching errors. Always confirm vehicle compatibility with the listing chart before ordering.

How do these coils and plugs improve engine performance?

Replacing worn coils and spark plugs restores consistent spark and combustion control, which helps the engine run smoothly under varied loads. Fresh components reduce misfires, stabilize idle, and help the engine recover designed power delivery.

• Restores proper ignition timing and spark intensity for each cylinder
• Reduces misfires that cause power loss and rough idle
• Helps maintain fuel economy by promoting complete combustion

Which vehicles and years does this kit fit?

What’s included in the package and how are the parts prepared?

The box contains four ignition coils and four pre-gapped spark plugs arranged for one-step installation. Parts are inspected to match fitment specs and minimize installation time; check torque and plug gap during installation following vehicle service manual instructions.

• 4 × pre-gapped spark plugs tested for correct gap and thread fit
• Packaged to prevent damage in transit and labeled for quick identification

How should I troubleshoot after installing the kit?

After installation, clear any stored trouble codes and perform a short road test to verify stable idle and acceleration. If a check-engine light returns, re-check electrical connections and coil seating, then scan for persistent cylinder-specific codes.

• Clear diagnostic codes and restart the engine to confirm normal operation
• Listen for smooth idle and check for absence of misfire or hesitation
• Re-scan for fault codes; address cylinder-specific errors if they reappear
