Air Intake Hose. Porsche 928 S2 4.7L 1985-1986

Air Intake Hose.
The Porsche Air Intake Hose is a genuine OEM replacement that connects the air filter housing to the throttle body or intake manifold, ensuring clean and measured airflow reaches the engine. Designed to handle heat, vibration, and under-hood conditions, this hose maintains the smooth airflow necessary for proper engine performance.

Fits:

• Porsche 928S2 4.7L 1985-86

What This Product Does:
The air intake hose is a key component of the Porsche engine air intake system. It connects parts of the intake assembly, ensuring that clean, filtered air flows smoothly from the air filter housing into the throttle body or intake manifold.

Functions:

• Directs filtered air into the engine for combustion.
• Maintains smooth airflow without leaks or turbulence.
• Designed to withstand heat, vibration, and engine bay conditions.
• Ensures proper air/fuel mixture for efficient combustion and performance.

Symptoms Of A Faulty Air Intake Hose:
Over time, rubber intake hoses can degrade due to heat, oil vapors, and engine vibration.
Warning signs include:

• Cracks or splits visible on the hose surface.
  
• Hissing or whistling noises under acceleration.
  
• Check engine light (CEL) due to unmetered air leaks.
  
• Rough idle, poor acceleration, or hesitation.
  
• Reduced fuel efficiency caused by incorrect air/fuel mixture.
  
  

Why Replacement Matters:
A damaged air intake hose allows unfiltered or unmetered air to enter the engine, leading to poor performance, potential engine damage, and inaccurate readings from the mass airflow sensor.
Replacing with a genuine OEM Porsche intake hose ensures:

• Proper airflow and engine efficiency.
• Leak-free connection between intake components.
• Long-lasting durability with factory-correct fitment.
• Restored smooth performance and reliability.
