OE Fine Wire Double Iridium Spark Plug

The Bosch 96345 is a Double Iridium spark plug engineered to provide both high performance and extended longevity, representing advanced original equipment (OE) technology. The center electrode is an iridium-alloy firing pin, and the ground electrode has a laser-welded inlay with an iridium alloy, contributing to a significantly longer service life—up to four times that of standard copper spark plugs. Its construction utilizes 360-degree continuous laser welding for increased durability. Further enhancing its performance and reliability, the Bosch 96345 incorporates a copper core to resist pre-ignition and fouling by providing a broader heat range. The spark plug comes pre-gapped and features nickel-plated threads, allowing for quick installation without the need to adjust the gap or apply anti-seize. The specifications for the Bosch 96345 include a 14mm thread diameter, a 16mm hex size, and a 19mm reach. It has a J-gap ground configuration and a non-projected insulator type. The manufacturer's heat range is 5, and it is designed as a 4-cycle spark plug. This plug is intended for automotive applications and is not for outdoor power equipment.
