CSF Porsche 911 Carrera / GT3 / GT3 RS (996) / 986 Boxster (Center) All-Aluminum Radiator

CSF has over 5 decades of experience manufacturing radiators, so when it comes to keeping your engine cool and your 996 Carrera, GT3, GT3 RS, or 986 Boxster running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high-horsepower builds and race vehicles needing added cooling performance in demanding motorsport environments.

The 2-row, 42mm core uses CSF's exclusive B-Tube technology. Rather than a regular oval "O"-shaped tube, a specially engineered "B"-shaped tube is carefully formed and brazed over the seam, increasing heat transfer surface area by approximately 20% over regular tubes while allowing for thinner, lighter aluminium construction that's genuinely stronger than a normal welded design, delivering true dual liquid laminar flow. Paired with 6.5mm multi-louvered fins precisely aligned and wind-tunnel tested for maximum heat rejection, and CNC-machined, welded OE-style brackets for lasting durability, this is a genuine drop-in fit requiring no modifications to install. Inlet/outlet connections match the OE connections exactly, so you can reuse factory or aftermarket hoses.

Works with: OE mounting points and hose connections. Pairs with CSF's matching Left/Right Side radiator (#7044, fits either side) for a complete cooling system upgrade.
