Product Information
CFS Aluminium Radiator air conditioning (Air Con) condenser.
CSF has decades of experience designing and manufacturing A/C Condensers, and has once again applied modern design and manufacturing techniques to these classic Porsche platforms. The result is a condenser that fits perfectly, outperforms the factory system by a significant margin, and costs less than a new OEM unit

Fits:
Porsche 996 911 (Carrera, 4, 4S, Targa, & GT3) 1999-2005
Porsche 986 Boxster (Base, S, Roadster, & Roadster S) 1997-2005

OEM Part Numbers: 9975739101, 99657311100

The CSF 996/986 Condenser utilizes a modern parallel-flow core design similar to the original OE unit. However, the CSF 18mm 8-channel microtube core offers better flow and more surface area contact for superior heat transfer. The 8mm tall multi-louvered fins further improve heat transfer over the basic fin design of the OE unit. Together, these features offer better heat dissipation for the refrigerant while increasing airflow to the radiators behind them.

Key Differences and Improvements:
• Increased performance: Approximately 5% better performance than a brand-new OEM condenser and much larger improvement over a clogged or dirty unit that has been installed for some time.
• More airflow to the radiator behind the condenser for better engine cooling performance
•  Improved Durability: More robust design and construction materials
•  Less Expensive: Around half the price of a new Genuine Porsche unit

Why Upgrade?
Whether you are restoring a 996 or 986 to show-car condition or upgrading your weekend toy for more comfort, CSF’s OEM+/Performance A/C Condenser is a no-brainer. It is a straight forward plug-and-play installation, more efficient, and built to last.

Porsche 996 / 986 OEM+ Performance A/C Condenser Features
•  Made with a Dual Pass Cross Flow CSF A/C Parallel Condenser Core
•  Super-High Pressure 18mm 8-Channel Microtube for Optimal Flow and Maximum Surface Area Contact
•  26 Rows of Cooling Tubes and paired with 27 Rows of 8mm Tall Multi-Louvered Fins
•  Laser Cut Mounting Brackets and OEM Style Block Fitting Connector
•  100% All Aluminum Construction
•  Satin Black Finish
•  True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications
•  Individually Leak and Pressure Tested
•  2-Year Limited Warranty

About Radiators

Porsche Performance Radiators - Engine Cooling & Thermal Control Upgrades

Radiators are a critical part of the engine cooling system, responsible for dissipating heat and maintaining optimal operating temperatures. In performance-driven, tuned, or high-mileage Porsche engines, upgraded radiators play a vital role in preventing overheating, reducing thermal stress, and protecting engine components under sustained load.

Available from Design911, Porsche performance radiators are engineered to deliver increased cooling efficiency, improved airflow, and enhanced durability—making them essential upgrades for road, track, and high-performance applications.

What Do Radiators Do?

Radiators regulate engine temperature by transferring heat away from the coolant.

Core Functions:

  • Dissipate engine heat efficiently.
  • Maintain stable operating temperatures.
  • Prevent overheating under load.
  • Support consistent engine performance.
  • Protect internal engine components from heat damage.

Effective cooling is essential for engine reliability and longevity.

Why Do Radiators Fail?

Standard radiators can degrade over time due to age, contamination, and increased thermal demand. Common failure causes include:

  • Internal blockage from debris or sediment.
  • External fin corrosion or damage.
  • Coolant leaks from plastic end tanks or seals.
  • Reduced efficiency due to age and contamination. 
  • Increased heat load from tuned or track-driven engines.

A failing radiator can lead to overheating, coolant loss, and serious engine damage if left unresolved.

Why Upgrade to a Performance Radiator?

Performance radiators are designed to handle higher thermal loads more effectively.

Upgrade Benefits:

  • Increased cooling capacity and heat dissipation.
  • Improved airflow and coolant flow efficiency.
  • Stronger materials for enhanced durability.
  • Reduced risk of overheating during spirited or track driving.
  • Ideal upgrade for tuned and high-output engines.

Upgrading the radiator helps protect engine reliability while supporting performance enhancements.

Highlights

  • Porsche performance radiator upgrades
  • Improved cooling efficiency and heat management
  • Designed for tuned and high-performance engines
  • Enhanced durability and long service life
  • Essential upgrade for track and performance use
