YATO YT-08163 spark plug wrench 3/8″ 14mm 310mm
YATO YT-08163 spark plug wrench 3/8″ 14mm 310mm
The YT-08163 spark plug wrench from YATO is designed for installing and removing 14mm spark plugs. Its 310mm length and integrated extension facilitate access to spark plugs deeply embedded in the cylinder head, especially in areas where a standard socket is too narrow.
The thin-walled, 12-point design allows for work in tight spaces, while the built-in joint increases flexibility in tool positioning. The wrench is compatible with ratchets and wrenches with a 3/8" (9.5 mm) drive.
A built-in magnet holds the spark plug inside the socket, making it easy to remove after unscrewing and easy to reinsert during assembly. The tool is made of CrV chrome vanadium steel, and the satin chrome finish helps protect the surface from corrosion.
