CSF High-Performance Left Radiator for 992 Porsche 911 Carrera / GT3 and GT3 RS / Sport Classic / Targa / Turbo and Turbo S [7241]

CSF High-Performance Left Radiator for 992 Porsche 911 Carrera / GT3 and GT3 RS / Sport Classic / Targa / Turbo and Turbo S [7241]

CSF expands its industry-leading Porsche cooling portfolio with the introduction of a High-Performance Left Radiator for the 992-generation 911, including 992.1 and 992.2 variants of the Carrera, GT3, GT3 RS, Sport Classic, Turbo, and Turbo S. As more 992 owners take their cars to the track or build them for spirited driving, the limitations of the factory cooling system — particularly on models without the OEM center radiator — are becoming increasingly apparent. In response, CSF now offers a complete high-performance solution with Left, Right, and Center Radiators designed for maximum efficiency and reliability. Trusted by thousands of Porsche enthusiasts worldwide, CSF cooling components have become the go-to upgrade across water-cooled 911s, Boxsters, Caymans, and Cayennes. With advanced thermal technology and modern manufacturing techniques, CSF delivers the most efficient drop-in fit radiators available for Porsche applications.

Why 992 Owners Should Upgrade

• Upgraded cooling systems aren’t just reserved for race cars or dedicated track builds — every 911 owner can benefit from enhanced thermal performance. To develop the optimal cooling solution for the 992-generation 911, CSF leveraged its strategic partnerships with world-class tuners, builders, and motorsport teams. Collaborating with respected names such as M-Engineering, ES Motor, and Pacific German has provided CSF with valuable insight into the strengths and weaknesses of modern Porsche platforms, along with real-world testing and validation for new products.
  • Extends engine life by maintaining optimal coolant temperatures
  • Maintains power output by enhancing cooling efficiency
  • Eliminates performance limitations during demanding driving conditions
  • Provides peace of mind with superior construction and durability

Design & Engineering

• CSF’s high-performance radiators help eliminate the risk of overheating through advanced engineering. These units feature oversized 2-row, 42mm aluminum cores that increase fluid capacity and significantly improve heat dissipation. When paired with CSF’s exclusive B-Tube Technology, heat transfer is increased by 20-25%. Additionally, the use of ultra-efficient 5mm multi-louvered fins enhances airflow through the core, delivering maximum cooling performance in even the most demanding conditions.
  • 20-25% increase in heat transfer efficiency using CSF’s new 5mm fin & exclusive B-tube technology
  • Improved cooling performance to support higher-boost and bigger-turbos as well as additional heat generated by high-performance driving and racing
  • Engineered to withstand extreme conditions, providing reliability where it matters most
  • Designed to fit perfectly in the OE location utilizing the factory ducting, mounting system, and A/C Condensers
  • Whether you’re building a street sleeper or prepping for your next track day, CSF’s 992 Radiators are engineered to handle the heat and then some

CSF vs OEM

• Factory Porsche radiators utilize single-row aluminum cores with plastic end tanks — a standard OE design that performs adequately for daily driving but leaves performance on the table. To further limit thermal capacity, Porsche omitted the center radiator from most 992 models, with the exception of the Turbo, Turbo S, GT3, and 992.2 GTS Hybrid. This omission has led many owners to experience elevated engine temperatures during spirited or track use, sometimes resulting in overheating within just a few laps.

The CSF Advantage

• To address these issues, CSF radiators incorporate the latest 5mm multi-louvered fin technology, significantly increasing surface area for heat exchange while maintaining efficient airflow. The 42mm 2-row aluminum core boosts coolant volume and heat dissipation capability, while CSF’s proprietary B-Tube Technology enhances thermal conductivity by approximately 15% over standard oval tubes — with up to 25% total improvement when paired with the new fins. The TIG-welded, 100% all-aluminum construction increases structural integrity, ensuring durability under extreme conditions. Designed as a direct replacement, CSF’s radiator installs in the factory location with no cutting or modifications required.

5mm Core Upgrade

• CSF is committed to delivering the most advanced cooling technology available. The introduction of its new 5mm fin design in late 2023 marks another leap in thermal efficiency, surpassing even the brand’s proven 6.5mm fins. Known for pushing their vehicles to the limit, Porsche owners can trust CSF radiators to deliver uncompromising performance and reliability under the most extreme driving scenarios.

Plug and Play Installation

• Each CSF radiator is engineered for plug-and-play installation, replacing the OEM unit seamlessly. The drop-in fit design allows for installation in just 2-3 hours and provides a substantial upgrade in engine cooling performance and long-term durability.
