Replacement hinge pin for a missing fusebox hinge. PETG is inferred for toughness and electrical-box service conditions; ABS is an alternative for higher heat. Verify hinge travel, retention and electrical clearance.

Replacement cover for the battery power-terminal box. Confirm cable clearance, latch engagement and electrical isolation before use. ABS is inferred for engine-bay heat and rigidity; ASA or a suitably rated engineering polymer are alternatives.

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.

Replacement small cover for the central relay board between the two relay boards behind the radiator. The creator identifies a 1992 Alfa Romeo 164 V6 2.0 Turbo; compare the original cover and relay-board layout before installation.

Replacement large cover for the pair of relay boards behind the radiator. The creator identifies a 1992 Alfa Romeo 164 V6 2.0 Turbo and exact source part number 164.00.40.852.01; compare the original cover and relay-board layout before installation.

Clip for 7.5 mm Lumenition Performance high-tension ignition leads used on Alfa Romeo Tipo 105 cars. Confirm lead diameter, avoid sharp bends, and keep the clip clear of hot or moving engine components.

Replacement cover for the Bosch idle-control valve sensor used on the 156 and 166. The creator designed it because the original cover is discontinued separately from the complete sensor.
