CSF High-Performance All-Aluminum Left Side Radiator for 2017-2025 Porsche 911 (991.2), 718 Boxster & Cayman (7086)

Fits select 2017-2025 Porsche 911 (991.2), 718 Boxster, 718 Cayman, and 718 Spyder models. This high-performance aluminum side radiator is engineered to replace the factory unit, providing superior thermal management for high-horsepower street builds and dedicated track vehicles.

The CSF 7086 features a heavy-duty 42mm 2-row core utilizing CSF's exclusive B-Tube technology. Unlike standard oval tubes, the B-Tube design is brazed at the seam for increased structural integrity, allowing for thinner, lighter aluminum with 15% more heat transfer surface area. Combined with 6.5mm multi-louvered fins, this radiator delivers approximately 20% better cooling efficiency than the OE component.

Designed for a true "drop-in" fit, this radiator includes CNC-machined brackets and OEM-style inlet/outlet connections to ensure compatibility with factory hoses, the AC condenser, and the fan shroud. Every unit is TIG-welded for durability and individually leak and pressure tested before receiving a smooth satin finish.
