CSF Volkswagen 06-09 Golf / GTI / 99-06 Jetta / GLI High-Performance Radiator

CSF has over 5 decades of experience manufacturing radiators, so when it comes to keeping your engine cool and your VW running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance 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. 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 genuinely stronger than a normal welded design. This delivers dual liquid laminar flow, paired with 6.5mm tall multi-louvered fins for maximum surface area contact. CNC-machined "quick-connect" inlet/outlet connections and CNC-machined brackets ensure a superb, durable fit, with 100% all-aluminium, TIG-welded construction throughout. This is a true drop-in fit requiring no modifications to install, accepting all attaching OEM components including quick-connect hoses, AC condenser, and mounting brackets.

Works with: OEM mounting points and quick-connect fittings across both platform generations covered by this listing.
