The DENSO IX24B Iridium Spark Plug is engineered for dependable ignition, improved firing performance, and long service life in demanding engine applications. Manufactured by DENSO, this spark plug uses a fine iridium center electrode that requires less voltage to produce a strong, consistent spark. Its design supports efficient combustion and reliable starting across a broad range of operating conditions.
Iridium is significantly harder and more heat-resistant than conventional spark plug materials, withstanding temperatures up to 4,000°F. The 360-degree laser-welded electrode construction creates a secure seal designed to resist wear, while the tapered-cut ground electrode and U-groove promote a larger flame-kernel area for more complete ignition. These features help maintain stable performance in high-temperature and high-stress environments.
Designed for applications requiring the DENSO IX24B specification, this plug should be matched to the vehicle or equipment manufacturer’s recommended heat range, thread, reach, and ignition requirements before installation. It is suitable as a replacement spark plug where DENSO part number 5376 is specified. Verify fitment using the application catalog or the original spark plug specifications to ensure proper compatibility.
