Bosch FR5DC Nickel Spark Plug – One‑Piece Performance

The Bosch FR5DC is a single Nickel spark plug designed for high‑performance ignition systems in a wide range of vehicles. Its compact, one‑piece construction delivers reliable combustion and consistent power output across diverse engine configurations.

Key Technical Features

• Nickel Alloy Electrode: Provides excellent conductivity and resistance to high temperatures, ensuring long life and stable spark generation.
• Optimized Gap: Engineered for precise spark gap settings that match OEM specifications, delivering efficient fuel‑air mixture ignition.
• Durable Ceramic Insulator: Protects the electrode from heat and electrical stress while maintaining structural integrity under extreme operating conditions.
• Corrosion‑Resistant Coating: Extends service life by preventing oxidation in harsh engine environments.

Compatibility Overview

The FR5DC is engineered to fit a broad spectrum of vehicles, including but not limited to:

• Audi, Ford, Seat, and Fiat models with 1.6‑2.0 L engines.
• Alfa Romeo and Caterham cars requiring the 0242245536 part number.
• Various Citroën, Nissan, and Volkswagen models that call for a nickel spark plug of this specification.

Installation Guidelines

1. Remove the Old Plug: Use a spark plug socket and ratchet to unscrew the existing plug, taking care not to damage the cylinder head.
2. Inspect the Socket: Ensure the socket is clean and free of debris that could affect torque application.
3. Set the Correct Gap: Verify the spark gap with a gap gauge; adjust if necessary before installation.
4. Tighten to Specification: Apply torque according to manufacturer’s specifications, typically around 100 in‑lb (1.35 Nm) for most engines.
5. Check the Spark Plug Wire or Coil: Ensure proper seating and secure connection of the ignition coil or wire harness.

Performance Benefits

• Enhanced Combustion Efficiency: Nickel electrodes maintain a stable spark even under high compression, improving fuel economy.
