In response to a new spark plug being used in one of the world's most popular vehicles, the Ford F-150 pickup truck, SK Hand Tool introduces their 4419 Spark Plug Socket. The new 9/16" socket is specially designed to accommodate the longer, slimmer spark plug design. This new plug design stems from a desire for more engine power while consuming less engine space. Features of the socket include:
- A longer design for added reach and easier access.
- A rubber insert that provides a more secure, soft grip on the hex without damaging the spark plug.
- An external hex bolster for added wrench torque.
