CSF Porsche 911 (997) / GT3 / 987 Boxster / Cayman High-Performance Radiator - Left Side

CSF's High-Performance Radiator for the 997/987 platform isn't just built for the street - it's genuinely raced. Track tested at extreme temperatures of 110°F (43°C), this radiator has proven itself with first-place finishes in the Pirelli GT3 Cup, POC, and PCA series, as well as at the Nürburgring - real motorsport credentials, not just marketing claims.

Full aluminium construction delivers a 40% increase in cooling capacity and 15-25% improvement in cooling efficiency over the factory unit, while eliminating the OEM's plastic end caps entirely - a well-documented weak point prone to cracking and leaking, especially on higher-mileage cars where bent or clogged fins from age and debris further reduce cooling effectiveness. The 2-row, 42mm core uses CSF's exclusive B-Tube technology, delivering approximately 20% more efficiency than a conventional tube design, paired with 6.5mm multi-louvered fins for maximum surface area contact. CNC-machined, welded OE-style brackets and OEM-style machined inlet/outlet connections ensure a genuine plug-and-play fit, finished with a smooth satin coating and individually leak and pressure tested before shipping.

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