The Bosch OE Fine Wire Spark Plug family consists of Double Iridium, Double Iridium Pin-to-Pin, Iridium, Double Platinum and Platinum spark plugs. Built around Original Equipment (OE) technology, these spark plugs have an OE-specific design and are manufactured to meet or exceed OE requirements. As direct injection continues to grow across all makes (Domestic, Asian, and European vehicles) and as ignition systems continue to increase in voltage output, things like advanced ceramic technology, spark position and correct gap are more critical than ever. Bosch created this line of OE equivalent spark plugs for the aftermarket to address these performance requirements.
Bosch precious metal spark plugs are pre-gapped at the factory and do not require a gap adjustment. Adjusting the gap may damage the center and ground electrodes.
