If you're diving into an S54 swap for your E36, you know the importance of a solid cooling system. CSF has been in the game long enough to understand what these setups need, and they've really knocked it out of the park with this all-aluminum radiator. This isn’t just any radiator—it’s designed specifically for high-performance applications, so it’s built to handle the heat. The first thing you'll notice is the 2-row, 42mm ultra-high-performance core that maximizes airflow and heat dissipation. This isn’t just a numbers game; it’s about keeping your engine cool when you’re pushing it hard. The engineers at CSF have taken their expertise from previous models like the E36 and E46 and applied it here, making sure this radiator fits seamlessly into your setup. One of the standout features is the way it accommodates oil coolers. The S54 needs a beefier oil cooling system compared to the S52, so CSF has designed this radiator with adjustable mounting brackets to fit both CSF #8032 and #8240 oil coolers. They’ve even reduced the radiator height just enough to keep everything tucked away neatly, maintaining that factory look while ensuring performance. Now, if you’re considering switching to an electric fan (which I highly recommend for better performance), CSF includes brackets for a single 16-inch SPAL fan. Sure, you can stick with a clutch fan, but going electric makes everything easier and more efficient. And let’s be real, it looks cleaner too. On the construction side, this radiator is all about durability. It’s 100% aluminum with TIG-welded seams, and every unit is individually leak and pressure tested. You can trust that it’s going to hold up under pressure, and it comes with a 2-year limited warranty for peace of mind. Plus, the satin finish gives it that sleek, OEM+ look, and you even get two top covers—one black and one satin—to switch things up. Here are some quick specs: - Core Height: 550mm - Core Width: 414.5mm - Inlet and Outlet Diameter: 1.5 inches each - It’s designed for a drop-in fit, so you won’t have to make any modifications during installation. This radiator fits a wide range of BMW models, including the 316i, 318i, 325i, and the iconic M3 from '93 to '99. Whether you’re racing or just enjoying spirited drives, this radiator will keep your engine running cooler and more efficiently. So, if you’re serious about your S54 swap, this high-performance radiator from CSF is a no-brainer. It’s built for enthusiasts by enthusiasts, and it’s ready to handle whatever you throw at it.
