Product Details

The Dinan D640-0002 is a high-performance iridium spark plug engineered for BMW turbocharged engines requiring colder heat range plugs. This EU-manufactured plug features iridium construction for superior durability and consistent spark performance under demanding conditions.

Key Specifications:

  • Thread diameter: 12mm with 26.5mm reach
  • Heat Range 9 - runs 3 steps colder than OEM on N54 engines, 2 steps colder on N55 engines
  • Iridium center electrode for extended service life
  • Projected insulator design with ceramic construction
  • Factory gap: 0.5mm (pre-gapped)
  • Flat seat type with nut terminal configuration
  • 14mm bi-hex design for secure installation
  • Installation torque: 17 Nm (12.5 lb-ft)

Ideal for modified BMW applications with increased boost or performance tuning where cooler spark plugs help prevent detonation and maintain optimal combustion. The colder heat range makes these plugs particularly well-suited for Dinan performance packages and other high-output turbocharged BMW engines.
