Bosch OE Fine Wire Double Iridium Spark Plug 9614
Bosch 9614 is an OE Fine Wire Double Iridium spark plug built for direct replacement service in select Honda and Acura applications. It combines a fine-wire iridium center electrode with a laser-welded ground electrode to support consistent ignition performance and long service life.
OE Fine Wire Double Iridium Design
The Bosch OE Fine Wire Double Iridium line focuses on precise spark delivery and durability. This plug uses an iridium-alloy center electrode firing pin, a laser-welded ground electrode with iridium alloy inlay, and a tapered ground tip design to improve ignitability. The projected ceramic insulator, resistor design, and preset 1.1 mm gap support stable operation in modern 4-cycle engines.
