Find a Part By:

Searching for your parts in the DENSO part catalog is easy. Simply select the type of part you are looking for along with the year/make/model of your U.S. or Canadian vehicle. For vehicles in Latin America, please go here.


    Search for cross reference part numbers for other manufacturers of the parts you're looking for.

    Cross Reference information is provided as a guide only. Please refer to the "Applications" lookup tabs for more detail. Materials and designs will differ among brands, so plugs are not exactly alike. Always check with your OE service manual for proper installation and settings.

    In ordinary cars, use a spark plug with the same heat range as a normal spark plug. In highly tuned vehicles, select a heat range to suit the tuning level of the engine. (Ordinarily, the heat range of a highly tuned engine tends to be colder.)

    Refer to the following table to compare the heat range of the Iridium Power and other spark plugs.
