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.

        Ignition Wire Sets

        Ignition Wires
        Ignition Wires

        Superior dielectric and thermal qualities

        Factory-original fit, appearance, and performance

        World-class chemical and oil resistance

        Fit Right, Look Right, and Work Perfectly

        Identical OE End Caps

        Designed to “click” into place for easy installation and a secure fit. This allows the installer to “feel and hear” that a solid connection has been made, even when the connection is in a difficult-to-see location.

        Strong Connections

        Through a patented process, the terminals are attached to provide an extremely strong connection ensuring the cable and boot will not separate during removal and installation.

        Pre-cut to Exact Lengths

        Each wire in the set is pre-cut to exact length so the wire sets are ready to install right out of the box.

        All-Silicone Wires

        The 7 and 8mm ignition wires are SAE J2031 Class E rated, the highest quality wire used in the industry. These wires can withstand temperatures from -40° to 428° F and pass tests covering everything from electrical properties to shrinkage to chemical resistance and accelerated life testing.
