Specialty pipe interchanges with 3A and connects 65-71 oil tank (26mm fitting) to thermostat. Provides maximum clearance for fitting wide tires. Unlike the factory line that passes between the tire and the inner wheel well, this line arches above the tire to give superior tire clearance. The critical area between tank and tire is a purpose-formed hard line for maximum clearance. Cars 65-71 are highly recommended to use this line for improved tire clearance.

Engine Cooling Oil System & Pipes – Precision Cooling and Lubrication for Porsche Performance
The engine cooling oil system and pipes play a crucial role in your Porsche’s performance and reliability. These components deliver and regulate oil flow between the engine, oil cooler, and filter, maintaining stable oil temperature and pressure. By keeping the oil cool and circulating efficiently, they help prevent overheating, reduce friction, and ensure smooth engine operation — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality engine cooling oil system parts and pipes for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each component is engineered for precision fitment, high heat resistance, and long-lasting durability, ensuring your Porsche performs exactly as its engineers intended.
What Do Engine Cooling Oil System & Pipes Do?
The oil cooling system and its connecting pipes work
together to control temperature and maintain lubrication efficiency throughout
the engine. Their main functions include:
- Transporting
oil between the engine, oil cooler, and filter housing.
- Dissipating
excess heat from the oil to prevent breakdown under pressure.
- Maintaining
stable oil pressure for consistent lubrication.
- Supporting overall engine temperature regulation alongside the coolant system.
These parts ensure your Porsche’s engine oil stays at the ideal temperature and viscosity, protecting vital internal components from wear and damage.
Why Do Oil System Pipes and Components Fail?
Even with regular maintenance, oil cooling system components
can wear out due to heat, pressure, and age. Common causes of failure include:
- Corrosion
or cracking of metal oil pipes from long-term exposure to heat and
oil.
- Rubber
hose degradation from high temperatures or oil contamination.
- Leaks
at connectors or fittings caused by vibration or poor sealing.
- Blocked
or restricted flow from sludge or carbon build-up.
- Mechanical damage from debris or impact under the vehicle.
Signs of failure can include visible oil leaks, oil pressure warnings, overheating, or the smell of burning oil.
Why Replace Faulty Oil System Parts and Pipes?
A failing oil pipe or cooler line can cause oil loss, overheating, and even catastrophic engine failure if left unchecked. Replacing worn or damaged components ensures your Porsche’s oil circulation and cooling remain efficient and leak-free.
Benefits of replacement include:
- Restored oil flow and cooling performance.
- Prevention of leaks, overheating, and engine damage.
- Improved reliability and efficiency under all conditions.
- Manufacturer-quality materials for long-term durability.
All parts in this range are built from high-grade metals, reinforced hoses, and corrosion-resistant fittings, designed to meet or exceed factory standards for performance and longevity.
