Product Details
Bosch OE Fine Wire Double Iridium is part of Bosch’s OE Fine Wire Double Iridium line, which focuses on OE-style fitment with fine-wire electrode technology. The iridium-alloy center electrode and laser-welded ground electrode with iridium alloy inlay are designed to maintain consistent spark characteristics over time, while the tapered ground tip supports efficient ignition under load. This makes Bosch 9660 a practical choice for maintenance on vehicles that specify a preset-gap iridium plug.
