What It Helps Address

• Misfires caused by worn or eroded spark plug electrodes
• Hard starting from weak ignition output
• Rough idle related to inconsistent spark delivery
• Reduced throttle response from degraded plug performance
• Service intervals that call for a direct OE replacement spark plug

Installation Notes and Tips

Verify the engine application before installation and confirm the preset gap matches the OE specification. Do not gap this plug; the gap is preset. Use the correct 16 mm spark plug socket and install to the manufacturer’s torque specification for the vehicle. For Hyundai Kona, Veloster, Elantra, and Kia Soul applications, confirm the original plug type and heat range before service.

Quality Assurance

Bosch OE Fine Wire Double Iridium plugs are built to OE-style specifications for modern ignition systems and are backed by Bosch manufacturing standards. The design uses durable electrode materials and a ceramic insulator to support consistent service in the listed Hyundai and Kia applications.
