CSF 7047 High-Performance 2-Row 42mm B-Tube Left Side Radiator for Porsche 911/Boxster/Cayman 2005-2012

Fits select 2005-2012 Porsche 911 (997), Boxster (987), and Cayman (987) models. This unit serves as the left-side radiator replacement for models including the Carrera, GT3, GT3 RS, Targa 4/4S, Boxster S, Spyder, and Cayman S/R.

The CSF 7047 High-Performance All-Aluminum Radiator is engineered to provide superior heat rejection for high-horsepower builds and dedicated track vehicles. It features a heavy-duty 42mm, 2-row core utilizing CSF’s exclusive B-Tube Technology. Unlike traditional oval "O" shape tubes, B-tubes are formed from lighter aluminum and brazed over the seam, creating a structure that is both stronger and more efficient. This design increases the heat transfer surface area by approximately 15%, providing the cooling capacity of two smaller tubes within a single tube's footprint.

To further enhance thermal performance, the core uses 6.5mm multi-louvered fins that are precision-aligned for maximum airflow. This radiator is a drop-in replacement that requires no modifications to the vehicle, utilizing CNC-machined brackets and OEM-style inlet/outlet connections to ensure a perfect fit with factory AC condensers and fan shrouds.
