The DENSO X24ES-U Spark Plug is an original-equipment-quality ignition component designed for dependable performance in compatible automotive applications. Manufactured by DENSO, this spark plug uses a copper core center electrode to promote efficient thermal conductivity and help manage operating temperatures during engine operation. Its reliable construction supports consistent ignition and smooth engine performance when replacing a worn or fouled spark plug.
The X24ES-U model is 100 percent pre-fired to help ensure reliable operation from installation. A unique five-rib insulator helps reduce flashover and voltage loss, while the dual copper and glass seal bonds the center electrode and insulator together to create a gas-tight seal. These features help support dependable electrical insulation, durability, and consistent spark delivery in the intended vehicle fitments.
Use the DENSO X24ES-U, manufacturer part number 4099 and vendor part number 4099, only for applications specified by the vehicle or engine manufacturer. Confirm the correct model and fitment before installation, and replace spark plugs according to the recommended service interval. This DENSO replacement spark plug is suited to automotive maintenance, repair, and original-equipment replacement needs where the X24ES-U specification is required.
