155 Tipo 167

Two-piece replacement cover for the high-tension ignition leads where they run toward the ignition coils on the 1992–1997 Alfa Romeo 155 Q4. The lower structure is retained by the standard large countersunk screw; the plain top cover uses two recessed M3 socket-head bolts. Do not overtighten the bolts, and verify clearance from hot and moving engine components before use.

Clutch-alignment tool for Lampredi two-litre twin-cam engines, explicitly including the 155 Q4. The creator notes that a printed tool is suitable for occasional use.

Replacement headlamp-washer jet nozzles for the 155, created because the originals deteriorate in sunlight. The source supplies the standard nozzle and a spray variant.
