Sealey Double End Long Reach Spark Plug Box Spanner 16mm x 21mm

About this tool

The Sealey Double End Long Reach Spark Plug Box Spanner is a specialist tool designed for accessing and removing deep-seated spark plugs in confined engine bays. This double-ended spanner accommodates both 16mm and 21mm spark plug sizes, making it versatile enough to work across a wide range of vehicles and small engines. With its 300mm extended length, this long reach spark plug spanner provides the additional leverage and access required when standard socket sets cannot reach recessed plugs. The tommy bar hole allows for controlled, even torque application, reducing the risk of cross-threading or damaging delicate spark plug ceramics during installation or removal. Ideal for professional mechanics working on vehicles with restricted engine access, this tool is equally suitable for small engine repair on generators, lawnmowers, and other plant equipment. The dual-size design eliminates the need to carry multiple tools when servicing different makes and models.
