Product Details

The Autolite 437 Copper Non-Resistor Spark Plug is engineered to deliver quick starts and reliable power for automotive, small engine, and tractor applications. This spark plug features a non-resistor design, making it ideal for classic vehicles, older equipment, and applications where radio frequency interference is not a concern.

Key Features:

  • Copper core center electrode aids in thermal control and improves resistance to fouling
  • Specially engineered high nickel alloy center and ground electrode provides extended life
  • High alumina multi-rib ceramic insulator provides thermal conductivity and superior insulation for increased strength
  • Nickel-plated shell that is corrosion resistant for increased durability
  • Power tip extends further into the combustion chamber to aid in self-cleaning, reducing fouling at low RPMs and pre-ignition at high speeds
  • Copper-glass seal bonds insulator and terminal post center electrode together to ensure full required voltage at spark gap

Technical Specifications:

  • Thread Diameter: 14mm
  • Thread Pitch: 1.25mm
  • Seat Type: Gasket
  • Reach: 11mm (7/16")
  • Hex Size: 13/16" (21mm)
  • Terminal Type: Solid
  • Gap: 0.033" (0.85mm)
  • Heat Range: 3

Cross-references to Champion H14Y and H18Y spark plugs. Recommended torque: Cast iron heads 26-29 lb-ft, aluminum heads 15-22 lb-ft. Commonly used in vintage Ford tractors, Onan engines, and classic automotive applications requiring non-resistor spark plugs.
