AS2-25 Ener-GX™ Industrial Spark Plug

AS2-25 Ener-GX™ Industrial Spark Plug

NGK's Professional-Grade AS2-25 Ener-GX™ Industrial Spark Plug features a specially designed v-groove center electrode, improving ignitability and reducing quenching. The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. NGK's Professional-Grade plugs are designed to be reliable for high performance in harsh conditions and are rated "Best" on the durability scale.

Your Model Number, AS2-25:

  •  A = M18x1.5, Hex 22.2 (Thread and HEX size)
  •  S = 20.6mm (Thread Length)
  •  2 = Professional Grade
  •  25 = 0.25mm (Gap)

NGK knows that the needs for industrial spark plugs require quality, reliability and durability. Their spark plugs push the limits of performance and innovation, bringing the most advanced technology to today’s high-efficiency engines.

The "A-Type / Professional-Grade" spark plug design features:

  •  2.5mm center electrode tip
  •  3.0mm ground electrode pad
  •  Super-wide ground electrode
  •  Best durability
  •  Best for long operation on landfill and bio gas
  •  Best for very long operation on oil & gas

Standard Features:

  •  Durable Terminal - Ensures connection to coil every time; hard terminal performs even under the heaviest vibrations
  •  Durable Resistor - NGK’s glass-sealed resistor guarantees stable performance under high temperatures and high voltages
  •  Patented Insulators - Ensures dielectric and physical strength; patented in-house- made ceramic properties establishes proper heat transfer
  •  Strong Caulking - NGK’s cold-crimping technology provides absolute locking of insulator to shell, virtually eliminating the possibility of dislodging
  •  Stainless Steel Gasket - Provides enhanced sealing and thermal conductivity at high temperatures
  •  High Quality Thread and Plating - Superior quality nickel plating resists corrosion on the shell and ensures smooth installation
  •  Triple Sealing Technology - Airtight seal holds compression under heavy combustion
  •  Solid Copper Core Center Electrode - Deeply inserted in the center electrode for improved thermal conductivity
  •  Extra Wide Ground Electrode - Sophisticated patented nickel alloy performs under high temperature and pressure
  •  Patented 3-Layer Copper Core - Copper core technology ensures rapid heat transfer
  •  Optimized Insulator Shape - Ensures physical and thermal strength, and prevents side-spark
  •  Securely Welded Pad - Precious metal pad, adhered through NGK’s powerful welding technology, increases longevity of the spark plug
  •  Maximized Gas Volume Design - Ensures good combustion; wider design increases flame expansion after spark discharge
  •  New Generation Precious Metal - Provides superior resistance against electrode wear in high combustion temperature environments
