Radiators

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.

SET OF 2

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.
