CSF Porsche 911 Turbo / GT2 / GT3 (996/997) All-Aluminum Radiator - Left Side

Designed to perform on the street or at the track, CSF's High-Performance Left Side Radiator is a must-have upgrade for high-horsepower builds and race vehicles needing added cooling performance in demanding motorsport environments. It replaces the factory unit with a 2-row core built around CSF's exclusive B-Tube technology, delivering approximately 20% more efficiency than a conventional design.

Rather than a regular oval "O"-shaped tube, CSF's specially engineered "B"-shaped tube is carefully formed and brazed over the seam, increasing heat transfer surface area by approximately 15% 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 plug-and-play drop-in fit requiring no modifications to install. Inlet/outlet connections match the OE connections exactly, so you can reuse factory or aftermarket hoses without issue.

Works with: OE mounting points and hose connections - this is the left-side unit only.
