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.

Protective replacement cap for the Alfa Romeo 156 shock-absorber top. The creator only says it might fit Alfa 147 and GT, so those generations are withheld. ABS is inferred for exterior/under-bonnet heat, moisture and impact; PETG is an alternative.

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.

Alternative M6 and M4 adapters for fitting an aftermarket threaded shift knob to the standard shift rod. Use the M6 variant with an intact original thread; the M4 variant requires drilling and tapping a damaged rod. Confirm secure retention, full gear selection and no reverse-lockout interference before driving.

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.

Two solid filler blocks for the jack-point air gaps. The creator printed them at 100% infill in ABS as a lower-cost alternative to 0.25-inch and 0.125-inch ABS or Delrin sheet.
