CSF Porsche 911 (996)/ 986 Boxster All-Aluminum Radiator

Designed to perform on the street or at the track, CSF's High-Performance All-Aluminum Radiator is a must-have upgrade for high-horsepower builds and race vehicles needing added cooling performance in demanding motorsport environments. Genuinely practical from a stocking perspective, the same part fits either the left or right side of the car - meaning one spare covers both positions.

The 2-row 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 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 ultra-efficient 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 without issue.

Works with: OE mounting points and hose connections - fits both sides (Left and Right), sold individually.
