The DENSO X27ES-U spark plug is an original-equipment-quality ignition component designed for reliable performance in compatible automotive applications. Manufactured by DENSO and identified by manufacturer and vendor part number 4114, this spark plug features a copper core center electrode that promotes efficient thermal conductivity and helps support consistent heat control during engine operation.
The X27ES-U model is 100 percent pre-fired to help ensure dependable operation from installation. Its unique five-rib insulator design helps reduce flashover and voltage loss, supporting stable ignition performance under demanding conditions. A dual copper and glass seal bonds the center electrode and insulator together to create a gas-tight seal, helping protect internal components and maintain reliable service.
Designed as a replacement spark plug for compatible automotive applications, the DENSO X27ES-U should be matched to the vehicle manufacturer’s recommended spark plug specifications before installation. Confirm vehicle, engine, and application fitment to ensure proper compatibility. The brand is DENSO, the model is X27ES-U, and the manufacturer and vendor part number is 4114.
