DENSO Spark Plugs

The DENSO difference

DENSO has been setting the standard for spark plug technology since 1959. We develop all of our ranges in-house, and manufacture them in our own QS 9000 and ISO 9000 certified factories worldwide – with ‘zero defects’ as standard.

We also provide this outstanding OE quality to the aftermarket. Including Nickel, Platinum, Twin Tip and Iridium, DENSO Spark Plugs cover a complete range of continually updated references. Guaranteeing optimum engine performance, choose DENSO Spark Plugs for every automotive, motorcycle, marine and small engine application.

CAUTION! (Prohibited Usage of Spark Plugs)

  • Never use DENSO Spark Plugs in the engines for any aircraft, including airplanes, helicopters, gliders and drones. DENSO Spark Plugs are not designed and manufactured for any aircraft: use may result in a plane crash or other accidents due to engine malfunction.
  • Never use DENSO Spark Plugs listed in our catalogue in the engines for generators and gas heat pump air conditioning systems. These spark plugs are not designed and manufactured for such use. Such use may result in accidents, including power generation stop or heat generation stop. A separate catalogue for DENSO Cogeneration Spark Plugs specifically designed for generators (gas engines) is available. Please contact your DENSO representative for more information.
  • Never use DENSO Spark Plugs for gas burner ignition. DENSO Spark Plugs that we sell are not designed and manufactured for such use. Such use may result in ignition failure or equipment damage due to overheating.
