CSF Porsche 997/987 Left High-Performance Radiator

CSF #7047 Left All-Aluminum Radiator is a high-performance cooling upgrade developed for selected Porsche 997 911, GT3 and 987 Boxster/Cayman applications. Designed for street performance, motorsport and demanding driving conditions, it provides a durable all-aluminum alternative to the factory radiator.

The radiator features a 2-Row 42mm core with CSF's exclusive B-Tube Technology. The B-Tube design increases the available heat-transfer surface area while allowing efficient coolant flow through the radiator core. According to CSF, this technology delivers approximately 20% greater efficiency.

A 6.5mm multi-louvered fin design further increases surface-area contact and supports efficient airflow through the core, helping improve heat rejection during sustained high-load driving.

The #7047 features an all-aluminum construction with 100% TIG-welded end tanks, together with CNC-machined brackets and fittings for accurate fitment and durability. OEM-style inlet and outlet connections allow compatibility with OEM or suitable aftermarket hoses.

Designed as a true Drop-In Fit, the radiator accepts the OEM A/C condenser and fan shroud while retaining the factory installation layout. Installation can be completed without vehicle modifications.

CSF #7047 is specifically the Left-side radiator. It should not be confused with the corresponding CSF #7048 Right-side Radiator or CSF #7049 Center Radiator, as each unit occupies a different position within the Porsche cooling system.

Applications include selected Porsche 997 Carrera, GT3 and GT3 RS models, together with 987 Boxster, Boxster S, Boxster Spyder, Cayman, Cayman S and Cayman R models. Exact vehicle application should always be confirmed before ordering.
