The DENSO Iridium Spark Plug IX27B is engineered to deliver reliable ignition, strong firing performance, and long service life in demanding engine applications. Manufactured by DENSO and identified by manufacturer and vendor part number 5377, this spark plug uses a fine iridium center electrode to help reduce the voltage required for ignition while promoting consistent combustion. Its iridium construction withstands temperatures up to 4,000°F, supporting dependable performance under high-heat operating conditions.
Feature: The 0.016-inch iridium electrode enables efficient voltage transfer and improved firing performance. Feature: A 360-degree laser-welded electrode connection creates a durable seal designed to resist wear in severe operating environments. Feature: The tapered-cut ground electrode and U-groove configuration create a larger flame-center area to support reliable ignition and efficient combustion. Feature: DENSO quality manufacturing provides a dependable replacement option for vehicles and equipment specified for the IX27B spark plug.
