The spacer is designed to sit between the carburettor base (typically a SOLEX 40 PII-4) and the intake manifold on classic Porsche models - 356 B/356 C and 912, manufactured to match Porsche OE specification.

This spacer provides the correct separation and sealing interface, ensuring proper carburettor alignment, uniform port matching and preventing heat soak from the manifold into the carburettor. It is manufactured from a high-temperature-resistant to replicate the original design and maintain correct insulating properties.
Ideal for engine rebuilds, intake servicing or performance restoration, this spacer restores the intended clearance, port geometry, and sealing integrity required for reliable induction performance in classic Porsche engines.
Over time, the original spacer can deteriorate, warp or crack because of exposure to heat cycling, vibration and fuel vapour. A compromised spacer may lead to vacuum leaks, mis-metered fuel/air mixture, uneven idle or reduced performance.
Replace this spacer when:
• Performing a carburettor or intake manifold service or rebuild
• The original spacer is cracked, delaminated or missing
• Vacuum leaks or rough idle suggest induction sealing problems
• Restoring a classic Porsche engine to factory specification
Fitting new spacer ensures the correct spacing, proper sealing and authentic air-flow behaviour you need for lasting engine performance and reliability.
