Spark Plug Socket Set 14mm 16mm 18mm 21mm 3/8in Flexi Joint

A 4-piece spark plug socket set for removing and fitting common spark plug sizes during servicing and repair work. The set includes 14mm, 16mm, 18mm and 21mm sockets, with a 3/8in drive and universal flexi joint to help reach plugs in tighter engine bays.

Used for vehicle maintenance, routine servicing and engine work where access around the cylinder head can be awkward. Suitable for garage work, workshop use and home mechanics carrying out spark plug changes on a range of vehicles, especially where surrounding components make a straight socket harder to use.

Chrome vanadium construction gives the sockets the strength needed for repeated use, while the 3/8in drive makes them compatible with standard 3/8in ratchets and accessories. The universal joint helps the socket angle into position when plugs are set deeper into the head or partly obstructed by covers, pipework or intake parts. With four common sizes included, the set covers a useful range for regular maintenance and helps avoid switching between mismatched tools when servicing different vehicles.
