Oregon Universal Fit Spark Plug Wrench

The Arnold R-42-452 Extended Spark Plug Wrench is a single tool designed to handle the three most common spark plug sizes found on small engines. Whether you maintain a lawn mower, chainsaw, string trimmer, or other outdoor power equipment, this wrench simplifies spark plug replacement and inspection by eliminating the need to carry multiple tools or swap sockets.

Deep recessed spark plugs can be difficult to access with standard tools. This extended wrench solves that problem with its 7-inch length, allowing you to reach plugs without removing surrounding engine components. The hex drive design fits 5/8-inch, 3/4-inch, and 13/16-inch plugs—the three most common sizes for small engine spark plug maintenance.
