Product Details

The NGK 5246 (CMR4H) Standard Spark Plug is a resistor-type, nickel-alloy spark plug built to OE-quality standards for small engine and other non-automotive applications. NGK Standard plugs are known for reliable ignition and long service life. This short-style 10mm plug is also referred to as an NGK CMR4H spark plug.

Key Features:

  • Nickel alloy electrodes with a solid copper core for heat dissipation, conductivity and a broad heat range
  • Alumina silicate ceramic insulator for strength and heat transfer, with a five-rib design that helps prevent flashover
  • Triple gasket sealing to prevent combustion gas leakage past the shell
  • Cold-rolled threads to help prevent cross-threading and cylinder head damage
  • Trivalent metal plating for corrosion and anti-seizing protection, making installation and removal easier
  • Built-in 10k ohm resistor to suppress radio frequency interference
