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.

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

  OE Match Air Conditioning Condensers  (Left & Right) – 2x 9975739101
  OE Match A/C Desiccator / Receiver Drier – 94457314301
  All necessary mounts, fittings, and brackets for direct replacement -  99970743441 &  99970726240

This set is ideal for:
  Cooling system overhauls
  A/C performance restoration
  Radiator and condenser replacement due to damage or age
  Preventative maintenance on high-mileage vehicles

Water Cooling System Components
The OE Match dual water radiators (99610613181 & 99610613251) replicate the original Porsche engine cooling cores, providing efficient heat exchange to maintain stable engine operating temperatures. Built with robust aluminium cores and corrosion-resistant tanks, these radiators handle long-term thermal cycling and high engine loads.

Air Conditioning Condenser & Desiccator
The OE Match A/C condenser is engineered to fit the factory A/C system, matching the original dimensions, port locations, and cooling capacity required for proper refrigerant condensation. Integrated within this module is the desiccator (receiver drier) - a critical component that removes moisture and contaminants from the refrigerant circuit, protecting the compressor and optimizing system efficiency.

Together, the radiators and condenser form the front-mounted heat exchangers that manage both engine coolant and A/C refrigerant heat rejection. With correct fitment and performance characteristics, this set restores proper engine temperature control and air conditioning cooling performance to factory expectations.

All components in this set are OE Match quality - meaning they are engineered to match original Porsche forms, fitments, and performance.

About Air con condensers & desiccators

Porsche Air Conditioning Condensers & Desiccators | Efficient Cooling Performance & Climate Control Reliability

The air conditioning condenser and desiccator are essential components of your Porsche’s climate control system. The condenser cools and condenses refrigerant gas into liquid form, while the desiccator (or receiver-dryer) removes moisture and contaminants — ensuring efficient cooling and long-term A/C performance.

At Design911, we supply precision-engineered A/C condensers and desiccators designed to meet or exceed original performance standards. Built with high-efficiency cooling fins and corrosion-resistant materials, these components ensure dependable operation, consistent cabin comfort, and reliable refrigerant flow in all driving conditions.

Whether you’re repairing a leaking condenser or restoring a complete air conditioning system, our Porsche condensers and desiccators deliver the performance, durability, and efficiency expected from premium climate-control components.

What Do Air Conditioning Condensers & Desiccators Do?

Together, these components regulate temperature and protect the A/C system from moisture and contaminants.

Core Functions:

  • Condenser: Converts high-pressure refrigerant gas into liquid by dissipating heat.
  • Desiccator (Receiver-Dryer): Filters refrigerant and removes moisture to prevent internal corrosion or ice formation.
  • Maintains optimal refrigerant pressure and temperature balance.
  • Ensures cold, efficient air output inside the cabin. Protects the compressor and A/C valves from contamination damage.

Without proper cooling and moisture control, the air conditioning system can lose efficiency, leading to poor cooling, corrosion, or compressor failure.

Why Do Condensers & Desiccators Fail or Degrade?

Constant exposure to heat, vibration, and road debris makes condensers and desiccators prone to wear and corrosion. Over time, they can lose effectiveness or develop leaks.

Common Causes of Failure Include:

  • Physical damage from road debris or stone impact.
  • Corrosion from moisture or road salt.
  • Clogged fins or tubes reducing airflow and cooling efficiency.
  • Moisture saturation in the desiccator leading to internal freezing.
  • Age-related wear causing refrigerant leaks or reduced pressure.

When these parts fail, symptoms include reduced cooling performance, A/C warning lights, foggy windows, or compressor noise — clear signs that replacement is required.

Why Replace Your Porsche A/C Condenser & Desiccator?

Replacing worn or leaking A/C components restores efficient cooling, improves air quality, and protects the compressor from costly damage. Upgraded units provide enhanced thermal transfer and durability for consistent year-round comfort.

Key Benefits:

  • Restores full air conditioning performance and reliability.
  • Prevents refrigerant leaks and system contamination.
  • Protects compressor and valves from moisture-related wear.
  • Improves heat dissipation and cabin cooling efficiency.
  • Precision-fit replacements for Porsche 911, Cayman, Boxster, Panamera, Macan, and more.
  • Ideal for system servicing, rebuilds, and preventative maintenance.

It’s recommended to replace the desiccator whenever the A/C system is opened or recharged to maintain long-term system protection.

Highlights

  • Premium Porsche A/C condensers and desiccators.
  • High-efficiency aluminium cores for superior cooling.
  • Corrosion-resistant coatings for long service life.
  • Filters moisture and debris for compressor protection.
  • Direct-fit designs for Porsche road and performance models.
  • Essential for restoring optimal air conditioning performance.
