CSF Porsche 911 Carrera / Turbo / GT3 RS & more (991) High-Performance Radiator - Left Side

The factory radiator on the 991 platform relies on plastic end caps prone to cracking and leaking over time - a genuine reliability concern whether your car sees track time or just daily driving. CSF's High-Performance Right Side Radiator eliminates that weakness entirely with full aluminium construction, delivering a 40% increase in cooling capacity and a 15-25% improvement in cooling efficiency over the factory unit.

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 actually stronger than a normal welded design. This achieves genuine dual liquid laminar flow, paired with ultra-efficient multi-louvered fins precisely aligned and wind-tunnel tested for maximum heat rejection. CNC-machined OEM-style mounting brackets and fittings, along with an all-aluminium race-style drain plug, round out a true drop-in fit - installing in the OEM location with no modifications necessary.

Works with: OEM mounting location and quick-connect hoses - this is the left-side unit only; most applications require both left (#7069) and right (#7070) radiators.
