Ideal for restoration projects, carburettor rebuilds, or hardware replacements, it restores factory-correct mounting geometry and reliability.

•  Function: Secures carburettor to intake manifold and maintains proper height / insulation
•  Position: Intake manifold / carburettor junction
•  Benefits: OE-spec fit, proper carburettor positioning, reduced heat transfer
•  Installation: Direct-fit replacement; torque to factory specification with new washers and gaskets

Carburettor spacer bolts are exposed to heat cycles, vibration, and corrosion, which can cause thread wear, warping, or loss of proper carburettor seating over time.

Replace this part when:
• Threads are stripped or corroded
• Carburettor mounting is loose or misaligned
• During intake or carburettor rebuilds
• You notice vacuum leaks or fuel irregularities

Installing a new Spacer Bolt ensures a tight, stable carburettor fit, restores correct intake geometry, and maintains smooth, reliable performance on your Porsche 356 or 912.
