High-Performance All-Aluminum Radiator

The CSF #7084 is a high-performance, all-aluminum radiator engineered to keep your Audi or VW MQB platform vehicle cool, whether on the street or the track. Its core features a 2-row, 42mm design utilizing CSF's exclusive B-Tube Technology. Unlike standard oval tubes, these 'B-tubes' increase the heat transfer surface area by approximately 15%, providing enhanced cooling efficiency and dual liquid laminar flow. The radiator also incorporates ultra-efficient, multi-louvered fins, precisely aligned and tested in a wind-tunnel lab to maximize airflow and heat dissipation. "Track-Spec" fins are 5mm tall for optimal surface area contact. The CSF #7084 is designed as a true "drop-in fit," requiring no modifications for installation. It comes with CNC-machined "quick-connect" inlet/outlet connections that match OE specifications, allowing the reuse of OEM hoses and other components. OE-style brackets and fittings are CNC machined and welded for superior fit and durability. A critical fitment note: This radiator has a thicker core (42mm compared to the stock 26mm) and will not fit with some aftermarket intercoolers that have core thicknesses greater than 60mm. It has been confirmed to work with intercoolers from AMS, APR, and 034 Motorsport. The radiator is compatible with a wide range of Audi and Volkswagen models from 2015-2026, including A3, S3, TT, Q3, Arteon, Golf, Golf R, GTI, Jetta GLI, and Tiguan, typically with the 2.0L Turbocharged L4 engine (refer to the application list for specific year ranges and chassis codes).
