CSF Porsche 911 Carrera / 981 Cayman / Boxster / 981 Cayman GT4) High-Performance Radiator - Right Side

Engine heat is the enemy when pushing your Carrera, Boxster, or Cayman hard - and the factory radiator's plastic end caps are a genuine reliability weak point over time, prone to cracking and leaking as they age. CSF's High-Performance Right Side Radiator eliminates that risk entirely with full aluminium construction, delivering a 40% increase in cooling capacity and 15-25% improvement in cooling efficiency over the factory unit.

The 2-row, 42mm 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, delivering approximately 20% more efficiency and genuine dual liquid laminar flow, while allowing for thinner, lighter aluminium that's actually stronger than a normal welded design. Paired with 6.5mm multi-louvered fins for maximum surface area contact, and built with 100% TIG-welded end tanks, CNC-machined brackets, and OEM-style machined inlet/outlet connections, this is a true plug-and-play drop-in fit - accepting the OEM AC condenser and fan shroud with no modifications required. Every unit is individually leak and pressure tested, and finished with a genuine one-hour hand-polished mirror finish.

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