Complete intake manifold pipe, SET OF 2. Porsche 911 2.4 S / 2.7 RS  ❭  91111006302

Complete intake manifold pipe, SET OF 2. 
Restore or upgrade the air intake plumbing on your classic Porsche 911 with this complete intake connection assembly. Designed for models with MFI/mechanical fuel injection, this intake pipe links the throttle/air-intake stack to the intake manifold, ensuring accurate airflow, reliable metering and correct fitment.

Fits:
Porsche 911 2.4 S / 2.7 RS 1972 - 1977

What This Product Does:

• The intake pipe (or intake connection) is a critical component in the engine’s air delivery system: it connects the throttle body, intake stack or air intake system to the intake manifold of the engine.
• It ensures a smooth, sealed, correctly shaped passage of air (and in the case of injection, the air-fuel mixture) into the cylinder head, maintaining correct airflow, avoiding leaks or turbulence that could upset fuel/air metering or engine response.
• On the era of 911 referenced (MFI mechanical fuel injection), proper intake piping is important for correct function of the injection system, throttle response, and overall engine performance.

Symptoms Of Wear, Damage Or When Replacement Matters:

• Air leaks or a hissing sound around the intake pipe, which can upset the injection/air-metering system, cause poor running, unstable idle or reduced performance.
  
• Poor throttle response, hesitation or mis-firing — if the pipe is cracked, partially blocked, or has missing components, it can degrade engine performance.
  
• Cracks, corrosion, or broken mounting tabs visible on the pipe or its flanges — especially for older vehicles where plastic/metal parts have aged.
  
• Difficulty fitting or aligning connections between the throttle stack and manifold — if the pipe is out of shape or damaged, it may be difficult to achieve correct installation or clean sealing.
  
  

Why Replacement Matters:

• Ensures correct airflow and engine performance: A damaged or sub-standard intake pipe can compromise air delivery, disrupt mixture control, and reduce engine efficiency or driveability.
  
• Improves reliability: Old or worn intake components can lead to leaks, performance issues or even engine damage (if mixture is upset or induction temperatures become erratic). Replacing with a correct part restores the system.
  
• Simplifies installation: Buying a “complete” intake connection (rather than patching multiple smaller pieces) saves installation time, reduces risk of missing parts, and ensures compatibility.
• Ensures fitment integrity: In older vehicles, mounting points may have degraded—installing a new pipe with correct flanges/hardware ensures everything aligns properly, reducing stress or potential leaks.
