CSF Porsche 911 Turbo/GT3/GT3 RS (991) Race Central Radiator

The factory central radiator on the 991 platform has a genuinely well-documented reliability problem — it's prone to both puncture and internal rotting, typically needing replacement every 5-7 years even under normal use. CSF's Race Central Radiator replaces it entirely with a proper all-aluminium upgrade, built to handle whatever forced-induction potential these engines can deliver rather than simply matching factory-plastic-tank longevity.

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 without sacrificing strength. Ultra-efficient multi-louvered fins are precisely aligned and wind-tunnel tested for maximum heat rejection, and CNC-machined OEM-style mounting brackets and fittings ensure a superb, durable fit. Every unit receives a genuine one-hour hand-polished mirror finish, and it's a true drop-in fit accepting all OEM attaching components, including quick-connect hoses — with a lifetime warranty backing the upgrade.

Works with: OEM mounting points and quick-connect hoses — no modification required, true drop-in fit.
