Spark Plug DENSO FC16HR-Q8

The DENSO Iridium Tough FC16HR-Q8 spark plug (part number 3524) is designed to ensure maximum performance and fuel efficiency in modern engines. The product features a unique iridium center electrode tip, which reduces the required ignition voltage, facilitating cold engine starts. Product parameters include a 12 mm thread diameter, 26.5 mm thread length (Long Reach), and a 14 mm hex size. A platinum insert on the ground electrode prevents premature wear, maintaining a stable spark gap throughout the entire operation period. The plug is ideal for new generation Toyota, Nissan, and Lexus engines, where ignition timing precision is critical for the correct operation of direct injection systems. The product is characterized by high corrosion resistance of the shell and improved insulation that eliminates surface flashover.
