A/C Intake Pipe. Porsche 955 Cayenne S / Turbo / Turbo S 4.5L 2003–06  ›  95557309202

A/C Intake Pipe.
The Porsche A/C Intake Pipe 95557309202 is a genuine Porsche replacement air-conditioning refrigerant suction line for selected Porsche Cayenne 955 models from 2003–2006.

Fits:

• Porsche 955 Cayenne S 4.5L V8 2003-06
• Porsche 955 Cayenne Turbo 4.5L 2003-06
• Porsche 955 Cayenne Turbo S 4.5L 2006>>  

After refrigerant has passed through the evaporator and absorbed heat from the cabin, it returns as low-pressure gas toward the compressor.

The suction line is responsible for:

• Carrying low-pressure refrigerant back to the compressor
• Maintaining a sealed refrigerant circuit
• Supporting correct low-side A/C pressure
• Allowing refrigerant to circulate continuously
• Helping maintain effective cabin cooling
• Providing the correct factory routing between A/C components
• Absorbing vibration and movement through its flexible sections
• Preventing refrigerant loss when properly sealed

Without a leak-free suction pipe, the A/C system cannot maintain the refrigerant charge and pressure balance required for effective cooling.

Symptoms Of Wear Or Failure:
Common symptoms of a damaged A/C suction pipe include:

• Weak air-conditioning performance
• Warm air from the cabin vents
• A/C cooling becoming progressively worse
• Refrigerant charge repeatedly becoming low
• Oily residue around the hose or fittings
• Visible refrigerant dye around a joint
• Hissing from escaping refrigerant
• Cracked or deteriorated flexible hose sections
• Abrasion or chafing
• Damaged or corroded metal sections
• Leaking connection points
• A/C compressor cycling abnormally
• System unable to maintain pressure

A suction-line leak can sometimes be very small, allowing the system to work temporarily after a recharge before cooling performance gradually deteriorates again.

Why Replacement Matters:
A damaged suction line prevents the A/C system from maintaining its correct refrigerant charge.

Continued refrigerant loss can lead to:

• Reduced cabin cooling
• Incorrect A/C pressures
• Frequent compressor cycling
• Loss of compressor lubrication circulation
• Increased compressor wear
• Complete A/C system shutdown

Replacing a leaking or damaged line restores a sealed path for refrigerant circulation.
