Product Details

When you're pushing your F-Chassis BMW's Gen 1 B58 engine harder, especially with upgraded turbos or for track use, the stock radiator can struggle to keep up. This CSF High-Performance Radiator is built to handle the extra heat. It's constructed entirely from aluminum with TIG-welded seams, offering better durability than the original plastic-tank design which can degrade over time and lead to leaks.

This radiator features CSF's exclusive 5mm tall fins with a multi-louvered design, increasing surface area for about a 20-25% improvement in heat transfer efficiency. This means it can help keep your engine coolant temperatures in check, even when you're running high boost or spending time on the track. It's designed to work seamlessly with your factory or aftermarket heat exchangers and offers a true plug-and-play installation with CNC machined brackets and OEM-style inlet/outlet connections, meaning no modifications are needed to fit it to your vehicle.

This radiator is a solid option for anyone looking to upgrade their cooling system for street performance or track days. It's individually leak and pressure tested to ensure reliability right out of the box. You'll get a hand-brushed satin finish and a 2-year limited warranty from CSF.
