As Porsche 997 and 987 models continue to age, corrosion, blocked cooling fins and road debris can significantly reduce the efficiency of both the engine cooling system and the air conditioning condensers. Replacing these components together restores cooling performance throughout the vehicle while reducing future labour costs and helping prevent overheating or air conditioning failures.

This complete upgrade package is ideal for road cars, fast-road builds, track day vehicles and full restorations.

Kit Contents

This complete cooling package includes:

• 2 x CSF OEM+ Performance Air Conditioning Condensers
• 1 x CSF Aluminium Left Water Coolant Radiator
• 1 x CSF Aluminium Right Water Coolant Radiator 

Together these components provide a complete front-end cooling system upgrade using premium CSF Performance products.

Why Replace the Cooling System Together?

The front-mounted radiators and air conditioning condensers are constantly exposed to:

• Road debris.
• Stone impacts.
• Moisture.
• Corrosion.
• Leaves and dirt blocking airflow.

Even when they appear externally clean, internal corrosion and blocked cooling passages can significantly reduce cooling efficiency.

Replacing all four units together provides:

• Maximum engine cooling performance.
• Improved air conditioning efficiency.
• Better airflow through the front cooling pack.
• Reduced coolant temperatures.
• Improved refrigerant heat dissipation.
• Increased long-term reliability.
• Lower overall installation costs compared with replacing components individually.

Radiators and pipes replacement kit.

This OE Match radiator and coolant pipe replacement kit is an all-in-one set of high-quality hoses and pipes engineered to replace the most common radiator and coolant delivery lines on Porsche 987 Boxster / Cayman and 997 Carrera models. Designed to match the factory routing and fitment, the kit includes radiator feed and return hoses, upper intake pipes, bypass lines, and related OE Match connectors required for a thorough cooling system service or overhaul.

Fits:
Porsche 997 Gen 1
Porsche 997 Gen 2

As engines age and operate under heat cycles and pressure, rubber hoses and coolant pipes can become soft, cracked, swollen, or restricted, leading to leaks, overheating, and reduced cooling performance. This comprehensive OE Match kit provides direct-fit replacements for the critical coolant lines between the radiator cores, coolant pump, thermostat housing, heater core, and engine block. Each component in the kit is manufactured to meet or exceed the original Porsche specification in hose inner diameter, bend geometry, wall thickness, and connection profile so that it installs cleanly into factory brackets and ports without modification. OE Match materials are chosen for long-term resistance to heat, coolant chemical exposure, and mechanical stress, ensuring durable performance throughout the life of the engine. This kit simplifies maintenance and repair by grouping all key radiator and coolant pipe replacements into one convenient solution, reducing parts hunting and ensuring that worn or deteriorated hoses do not compromise the cooling system’s integrity after other components (such as radiators or pumps) are serviced.

What This Kit Does:

The coolant and radiator pipes in this kit work together to:

• Carry coolant flow between the engine, thermostat, heater core, coolant pump, and radiator
• Maintain correct pressure and temperature balance across the cooling system
• Support reliable heat rejection through the radiator cores
• Prevent coolant loss and overheating due to brittle or collapsed hoses
• By matching OE geometry and fitment, these hoses help maintain efficient coolant circulation and stable operating temperatures during normal driving as well as spirited use.

The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.

Proper heat rejection helps:
• Maintain optimal engine operating temperature
• Prevent overheating under everyday and high-load conditions
• Support fuel efficiency and emission control
• Preserve engine component durability and longevity
