NGK 95856 Spark Plug
NGK Laser Iridium Spark Plug for Ford Performance
NGK Laser Iridium Spark Plug 95856 is built for OE-style ignition performance with durability focused materials and precise electrode design. It is a direct-fit spark plug for select Ford F-150 and Ford Mustang applications, including 2025 Ford F-150 and 2019-2022 Ford Mustang fitments listed below.
The Laser Iridium line combines an iridium-tipped center electrode with a platinum ground electrode pad on many applications to promote even wear in distributorless ignition systems. NGK also uses a high-grade ceramic insulator and copper core construction to help manage heat and support reliable starting.
