CSF Porsche 911 / GT2 / GT3 (991.2) / 718 Boxster/Cayman All-Aluminum Radiator - Left Side

CSF manufactures what is genuinely among the most advanced and efficient radiators in the industry for the 991.2/718 platform, using innovative tube and fin technologies with industry-leading testing methods to maximise airflow and heat dissipation. Designed to perform on the street or at the track, this High-Performance All-Aluminum 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 - a specially engineered "B"-shaped tube, carefully formed and brazed over the seam, delivering approximately 20% more efficiency than a conventional oval tube design while allowing for thinner, lighter aluminium construction that's genuinely stronger than a normal welded design. Paired with 6.5mm multi-louvered fins for maximum surface area contact, and finished with a smooth satin coating, this is a true plug-and-play drop-in fit with OEM-style machined inlet/outlet connections, sealing foam for optimised airflow into the core, and no modifications required for installation. Every unit is individually leak and pressure tested before shipping.

Works with: OEM AC condenser and fan shroud - this is the left-side unit only.
