CSF Porsche 991.2/718 Left Performance Radiator

CSF #7086 Left All-Aluminum Radiator is a high-performance cooling upgrade developed for selected Porsche 991.2 and 718 applications. Designed for demanding street, performance and track use, it provides increased cooling capability while retaining the factory radiator location.

The radiator features a 2-Row 42mm core with CSF's B-Tube Technology, engineered to increase heat-transfer surface area while maintaining efficient coolant flow. CSF states that its B-Tube technology increases tube heat-transfer area by approximately 15%, while the complete core design provides approximately 20% greater efficiency.

A 6.5mm multi-louvered fin design further increases the available surface area and promotes efficient airflow through the radiator core, supporting improved heat rejection during sustained high-load driving.

The #7086 uses an all-aluminum construction with 100% TIG-welded end tanks, combined with CNC-machined brackets and fittings for strength, durability and precise vehicle-specific fitment.

OEM-style machined inlet and outlet connections allow compatibility with OEM or suitable aftermarket hoses. The radiator also accommodates the OEM A/C condenser and fan shroud, maintaining the original cooling-system configuration.

Designed as a Drop-In Fit, CSF #7086 can be installed using the factory mounting configuration without vehicle modifications. Each radiator is individually leak and pressure tested before leaving the factory.

This is specifically the Left-side Radiator, designed to complement the corresponding CSF #7087 Right-side Radiator. Applications include selected 991.2 Carrera, Carrera S, Carrera 4, Carrera 4S, Carrera T, Carrera GTS and Targa models, together with numerous 718 Boxster and Cayman variants.

For Porsche owners seeking improved thermal management without changing the factory cooling-system layout, CSF #7086 provides a high-performance all-aluminum radiator solution for demanding road and track use.
