What This Product Does

This pipe provides the supply connection within the external oil-cooling circuit. It carries oil between the thermostat assembly and front cooler; temperature-dependent flow control remains the thermostat's job, rather than a function of the pipe itself.

Functions

• Connects the thermostat assembly and front oil cooler.
• Provides the specified supply route along the vehicle.
• Contains circulating oil within the connected pipework.
  
  

Technical Details

• Brand: OE Match.
• Part number: 96420713304.
• External oil-cooler pipework
  
  

Symptoms of Fault

• Fresh oil beneath the vehicle or on its undertray.
• Wet patches along the line or around its connections.
• Corrosion, rubbing damage or visible cracking.
• An oil smell following a journey.
• Recurring oil loss requiring investigation.
  
  

These signs can have other causes. Identify the active leak before deciding which component needs replacement.

Why Replacement Matters

Renewing a damaged or leaking supply line addresses oil loss at the affected pipe. Heat cycles, vibration and ageing connections can contribute to deterioration, so inspect adjoining fittings, supports and seals during the repair. OE Match's Porsche-focused replacement programme uses application and original-reference checks when identifying suitable components.

FAQs

Is this the thermostat?
No. It is the connecting oil supply pipe, not the temperature-control assembly.

Can a connection cause the leak?
Yes. Inspect the unions and sealing points as well as the pipe body before replacing parts.

Should nearby mounting parts be checked?
Inspect clamps and supports for deterioration or looseness, and renew damaged hardware as appropriate.

Does this replace both long oil lines?
This description identifies the supply pipe only; do not assume the separate return line is included.

What should be checked after fitting?
Inspect the repaired connections for fresh seepage after the system has been through a heating and cooling cycle.
