Bosch HR8MCV Super Plus Nickel Spark Plug Set of 4

The Bosch HR8MCV Super Plus Nickel Spark Plug Set of 4 is engineered for high‑performance ignition in modern gasoline engines. Designed with a robust nickel alloy electrode, this set delivers reliable cold starts, consistent spark energy, and extended service life across a wide range of vehicles.

Key Technical Specifications

• Model Number: 0 242 229 902 (HR8MCV)
• Electrode Material: Nickel alloy for superior conductivity and corrosion resistance
Heat Range: HR8 – suitable for engines with moderate to high compression ratios
• Thread Size: M 14 × 1.25 mm
• Spindle Length: 16 mm (standard for most passenger cars)
• Recommended Vehicles: Ford Focus, Mazda MX‑5, Volkswagen Golf, and many others that require the HR8 heat range

Performance Highlights

The Super Plus Nickel construction ensures a stable spark even under high temperature conditions. The nickel coating reduces electrode wear, allowing the plug to maintain optimal spark intensity for longer periods compared to standard copper plugs.

• Cold‑Start Reliability: Enhanced ignition energy guarantees smooth starts in cold weather.
• Longer Service Life: Nickel electrodes resist oxidation and erosion, extending the interval between replacements.
• Consistent Power Delivery: Maintains uniform spark voltage across all cylinders, improving combustion efficiency.

Installation & Compatibility

The set is pre‑torqued to 13 Nm, ensuring a secure fit without the need for additional tools. It matches the standard M 14 × 1.25 thread profile used in most modern engines, making it a drop‑in replacement for OEM plugs.

• Installation Steps:
  1. Remove old spark plugs with a socket wrench.
  2. Clean the cylinder head and inspect the spark plug wells.
  3. Insert the new HR8MCV plug, hand‑tighten, then torque to 13 Nm.
  4. Reconnect ignition leads and verify proper gap (typically 0.7–1.0 mm).
• Gap Settings: Refer to vehicle service manual; most HR8 plugs require a gap of 0.9 mm for optimal performance.
