CSF 2-Row 42mm Race Spec Aluminium Radiator - BMW 2 / 3 / 4 Series (B58 Gen 1)

The CSF 2-Row 42mm Race Spec Aluminium Radiator is built for Gen 1 B58-powered BMW 2, 3 and 4 Series models on the F2X and F3X platforms. The factory radiator has plastic tanks and a single-row 34 mm core, and with the heat exchanger mounted in front of it, coolant temperatures can climb high enough on track to trigger limp mode, especially with more boost or a bigger turbo. CSF's version uses a two-row 42 mm aluminium core with B-Tube cooling tubes and its latest 5 mm multi-louvred fins, which add 20-25% more heat transfer efficiency, and it works with the factory or an aftermarket heat exchanger. It is fully TIG-welded and mounts in the factory location with no cutting or modifications.

Features

• Two-row 42 mm core against the factory single-row 34 mm core

• 100% TIG-welded aluminium tanks in place of the factory plastic tanks
• CNC-machined mounting brackets and OEM-style inlet and outlet
• Works with factory or aftermarket heat exchangers
• Hand-brushed satin finish, individually leak and pressure tested
