Advantages and recommended use

Description and Key Advantages

The NGK 7957 glow plug, part of the high-performance D-Power range (reference DP56), is an OE-equivalent quality component designed to optimize cold starts for diesel engines. Its specific design for vehicles equipped with a diagnostic system (Fzg. mit Diagnose) ensures seamless integration with the engine's electronic management. Featuring an M4x0.70 threaded terminal, it guarantees a stable and durable electrical connection, minimizing energy loss thanks to its calibrated 1.4-ohm resistance.

Technical Specifications

  • Manufacturer range: D-Power (internal reference Y1005J).
  • Electrical data: 11 V voltage and 1.4 ohm resistance for precise heating.
  • Dimensions: Total length of 121 mm with a 27 mm thread length.
  • Thread: Main dimension M10 x 1.0.
  • Installation: 10 mm glow plug spanner size and threaded terminal connection.

Recommended Use

This glow plug is recommended for standard replacement across a wide range of vehicles, particularly for PSA (Citroën/Peugeot), Ford, Volvo, and the Fiat group (Alfa Romeo, Lancia, Abarth). It is a direct equivalent to manufacturer references 596064, 1473356, or 9651583680. Its use is strictly recommended for engines requiring a 10 mm spanner and a glow plug system compatible with onboard diagnostics, thereby ensuring reduced emissions and optimal battery protection during ignition phases.
