CSF High Performance Radiator - BMW G20 | G21 330i | 330e | G29 Z4 20i | 30i | M40i

CSF's High Performance Radiator is a direct upgrade for the B48 and B58-powered G29 Z4 and the G20/G21 330i and 330e. Built around a 2-row, 42mm core with CSF's B-Tube technology and new 5mm fins, it significantly increases cooling capacity over the factory radiator – ideal for tuned cars, hot climates and track use.

Fully TIG-welded aluminium construction, CNC-machined brackets and an OEM-style inlet and outlet make it a true plug-and-play installation, finished with a 1-hour hand polish.
