Inlet Manifold
By OE Match
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 356B 1959-63
- Porsche 356C 1963-65
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.
SET OF 4
Fits:
Porsche 912 1965 - 1969
Porsche 356 B/C 1600/S90/SC 1960 - 1965
Diagram ref no 2 (for 912) or 4 (for 356)
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.

OEMatch Inlet Manifold — Flow, Response, Refinement
OEMatch supplies inlet manifold items for Porsche models, combining replacement manifolds, gaskets and related seals with an extensive cross-reference catalogue to support fitment and servicing. These products are selected to help restore consistent airflow and engine responsiveness where an ageing or damaged inlet manifold affects performance.
Available Types
- Cast aluminium inlet manifolds
- Composite/plastic inlet manifolds
- Manifold gaskets and seal kits
Understanding OEMatch Inlet Manifold
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original inlet manifold.
OE (Original Equipment) refers to parts matching original specifications for the inlet manifold and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM inlet manifold engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The inlet manifold itself distributes intake air from the throttle body to each cylinder and helps balance pressure and flow for smooth idling and consistent combustion across the rev range.
Benefits Include
- Restores balanced airflow to each cylinder for stable combustion
- Improves throttle response and idle quality
- Replaces degraded seals to reduce vacuum leaks and emissions
Why Inlet Manifold Wear and Fail
- Heat cycling and material fatigue leading to cracks or leaks
- Carbon and oil buildup restricting runners and passages
- Deterioration of gaskets and seals allowing unmetered air ingress
The Importance of Replacing with OEMatch Inlet Manifold
A leaking or damaged inlet manifold can cause uneven air delivery, rough running and reduced efficiency. Replacing a compromised manifold restores consistent airflow balance, helps protect engine components from lean or overly rich running conditions and supports predictable throttle response for everyday driving and inspection tests.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Available with compatible gasket and seal kits for a complete repair
- Manufactured from materials chosen for heat resistance and sealing longevity
