As the legendary Porsche 964 and 993 models from the 1990s continue to mature, it is common for their original air conditioning systems to exhibit signs of wear and diminished efficiency. Issues such as leaking, clogging, and general underperformance are frequently encountered by owners. Moreover, many systems originally designed for R12 refrigerant now operate with the modern R134a, which inherently offers reduced cooling capacity. This transition often results in air conditioning that no longer meets the comfort expectations of today’s drivers.
CSF presents a meticulously engineered solution with the OEM+ Performance A/C Condenser tailored specifically for the Porsche 964 and 993 series. This product is designed to reinstate and enhance the air conditioning performance of your 911, ensuring a more comfortable and reliable driving experience without compromising the integrity of the classic vehicle.
Product Details
Design & Engineering
Original factory A/C condensers from the 1980s and 1990s were developed with materials and design standards suitable for the R12 refrigerant, which provided superior cooling efficiency compared to the environmentally friendlier R134a used today. Even brand-new OEM condensers cannot fully offset the performance loss associated with this refrigerant change.
Leveraging decades of expertise in designing and manufacturing advanced A/C condensers, CSF has collaborated with industry leaders such as A/C Solutions to develop this modern classic series condenser. Utilizing state-of-the-art design methodologies and manufacturing processes, CSF delivers a product that not only fits precisely but also surpasses the original factory condenser’s performance by a significant margin, all while being more cost-effective than a new OEM replacement.
CSF vs OEM
The CSF condenser for the 964/993 models incorporates a contemporary parallel-flow core design, which is substantially more efficient than the traditional serpentine style condensers found in the original equipment. This design advancement translates into notable improvements in cooling capacity and system reliability.
Key Differences and Improvements:
- Enhanced Performance: Approximately 5% superior cooling efficiency compared to a brand-new OEM condenser, with even greater gains over aged or clogged units.
- Optimized for R134a Refrigerant: Compensates for the inherent cooling power reduction due to refrigerant conversion, restoring system effectiveness.
- Improved Durability: Constructed with robust materials and advanced manufacturing techniques to ensure long-lasting performance.
- Cost Efficiency: Priced at roughly half the cost of a new Genuine Porsche condenser, providing excellent value without sacrificing quality.
