CSF is a leader in automotive cooling technology, with over a half-century of experience. Using that knowledge, they have developed this high-performance radiator that far surpasses the abilities of the stock unit. Starting with a two-row, triple-pass design for the coolest temperatures possible, this radiator features high-quality CNC-machined brackets and hardware. To finish it off, each radiator is hand polished to a mirror finish for that show-car shine. Best of all, it fits like the stock part, requiring no modifications for installation. If you're serious about performance, upgrade your radiator with this quality part from CSF.

Note: May require a tune to prevent check engine lights. This radiator does such a good job of keeping your BMW cool, that the ECU might think it's running too cool!
