The 2016 Hyundai Sonata generally uses iridium-tipped spark plugs, with NGK or Denso among the common brands. The exact part number depends on the engine variant (2.4L or 2.0L turbo) and the market.
Engine options for the 2016 Sonata
The 2016 Sonata offered two main engine configurations in many markets: a naturally aspirated 2.4-liter inline-4 and a 2.0-liter turbocharged inline-4. While both use iridium-tipped plugs, the precise plug specification varies by engine code and regional guidelines.

In short, confirm the engine code on your vehicle (or VIN) to determine the exact spark plug specification required.

Note that the exact part number and heat range must match your engine specification and market. Always verify compatibility with the vehicle’s service manual or Hyundai’s official parts catalog.
How to determine the exact plug for your car
To be sure you get the correct spark plugs for your 2016 Sonata, follow these steps:
- Identify your engine code (2.4L or 2.0L turbo) and the market where the vehicle was sold. This information is usually found on the engine label or VIN.
- Consult Hyundai’s official parts catalog or the vehicle’s service manual for the exact part number and gap specification.
- Match the spark plug to the engine’s thread size, heat range, and electrode design as specified for the direct-injection setup.
- Purchase the recommended plug and have them installed by a competent technician or follow the manufacturer’s torque and replacement guidelines.
Following these steps ensures you select the correct spark plugs for your particular 2016 Sonata variant.
Maintenance tips and replacement intervals
Spark plug maintenance for the 2016 Sonata varies by engine type and driving conditions. Many owners see replacement intervals in the range of several tens of thousands of miles, with turbo and direct-injection variants sometimes demanding attention sooner due to carbon buildup or harsher driving conditions.
- Signs you may need plugs include rough idle, misfires, reduced fuel economy, or difficulty starting.
- When replacing, use the recommended iridium plugs and the correct gap as specified by Hyundai for your engine variant.
Regular inspection and adherence to the manufacturer’s guidance help maintain performance and efficiency.
Summary
