Air intake suction hose. Porsche 928 78-91  ›  92811027204

The OE Match Air Intake Suction Hose is a replacement intake-air duct for selected Porsche 928 models from 1978 to 1991.

• Porsche 928 1978-91

Positioned within the front air-intake system, the hose connects the incoming intake tube or air guide to the air filter housing, helping channel outside air towards the engine's air filtration and induction system.

Over decades of engine-bay heat, vibration and repeated temperature cycling, the original intake ducting can become brittle, soft, cracked, misshapen or partially collapsed.

Replacing a deteriorated suction hose helps restore the intended intake-air route, maintains a secure connection to the air filter housing and prevents ageing ducting from restricting or disrupting airflow.

What This Product Does:
The Air Intake Suction Hose forms part of the Porsche 928's incoming-air ducting.

Its primary functions are to:

• Guide outside air towards the air filter housing.
• Connect the intake tube or air guide to the airbox.
• Maintain an enclosed and correctly routed intake path.
• Help reduce intake of unnecessary hot engine-bay air.
• Prevent loose debris entering through damaged ducting.
• Maintain the intended cross-sectional area for airflow.
• Prevent soft or deteriorated ducting from collapsing.
• Restore the original intake-system arrangement.
• Replace cracked, torn or distorted original hoses.

• Visible cracks.
• Splits or tears.
• Hardened material.
• Soft or weakened sections.
• Hose deformation.
• Flattened areas.
• Partial collapse.
• Poor fit at the airbox.
• Loose connections.
• Hose slipping out of position.
• Surface deterioration.
• Previous tape repairs.
• Intake restriction at higher engine load.
• Unusual intake noise.

• Correct intake-air routing.
• Proper airbox connection.
• Full intake duct cross-section.
• Reduced risk of duct collapse.
• Reduced intake of hot engine-bay air.
• Protection from loose debris.
• Correct engine-bay appearance.
• Long-term intake-system reliability.
