BOSCH 0 242 129 515 Spark Plug

Product Overview

The BOSCH 0 242 129 515 Spark Plug is a high‑performance ignition component designed for modern gasoline engines, particularly those found in Hyundai and Kia models. It features Bosch’s renowned Nickel alloy electrode, which delivers excellent conductivity and resistance to wear, ensuring reliable spark generation under demanding operating conditions.

Key Technical Specifications

• Model Number: 0 242 129 515 (also referenced as YR8SEU)
• Electrode Material: Nickel alloy for superior durability and heat tolerance.
• Heat Range: Medium‑to‑high, suitable for engines with moderate to high compression ratios.
• Thread Size: 14 mm × 1.25 mm (standard automotive spark plug size).
• Length: 58 mm, providing a balanced reach between the electrode and the engine head.
• Installation Torque: 13–15 Nm (recommended by Bosch for optimal sealing).

Compatibility

This spark plug is engineered to fit a wide range of Hyundai and Kia engines, including but not limited to:

• Hyundai i20, i30, Elantra, Accent, Veloster, ix20, and Solaris
• Kia Ceed, Rio, Carens, Soul, Venga, Cerato, and other models with similar engine families.

Its universal design allows it to be used in both petrol engines and mild‑hybrid powertrains that require a conventional spark plug for the combustion chamber.

Performance Benefits

• Consistent Spark: The nickel electrode maintains a stable spark even at high engine temperatures, reducing misfires and improving fuel efficiency.
• Long Service Life: Nickel’s resistance to corrosion and wear extends the plug’s lifespan compared to standard copper plugs.
• Improved Engine Response: A reliable ignition source translates into smoother throttle response and better acceleration.
• Reduced Emissions: Efficient combustion leads to lower exhaust emissions, aiding compliance with stringent environmental regulations.

Installation Guidelines

1. Warm the engine slightly to reduce thermal shock during installation.
2. Use a spark plug socket and torque wrench; tighten to the specified 13–15 Nm.
3. Apply a small amount of anti‑seize compound on the threads if recommended by the vehicle manufacturer.
4. Check for proper clearance between the spark plug head and the valve train before final tightening.

Maintenance Tips

• Inspect plugs every 20,000–30,000 km or as part of routine service intervals.
• Look for signs of fouling (black deposits) or excessive wear; replace if necessary.
• Avoid over‑tightening, which can damage the threads or crack the ceramic insulator.
