This spark plug shaft spacer ring with a thickness of 0.5 mm supports correct positioning of the spark plug in the cylinder head. The component compensates play in the shaft and helps achieve a stable seal. It suits specific engine designs that use similar dimensions and connections as certain Citroën vehicles. The ring limits unwanted movement of the spark plug and contributes to even force transfer when tightening. This part is used during maintenance or overhaul of engines where the spark plug shaft dimensions need correction. It supports consistent assembly and can help extend the functional reliability of the spark plug mounting area.
