do88 07-13 BMW 135i/335i N54/N55 (E82/E88/E9X) Manual Radiator

do88 is known for making well-built cooling components for performance applications. This manual radiator is designed specifically for the 07-13 BMW 135i and 335i models equipped with the N54 or N55 engines, covering chassis codes E82, E88, and E9X. If you're pushing your BMW hard, especially on the track or in demanding street conditions, keeping engine temperatures in check is crucial for performance and longevity. This radiator is a direct replacement for your stock unit, but with a significant upgrade in cooling capacity.

This radiator features a core that is 50% larger than the original equipment, meaning it can dissipate more heat. The construction uses aluminum for the tanks and core, which is lighter than stock and offers excellent thermal conductivity. It's built with a dual-core design, providing more surface area for air to pass through and cool the coolant. The tanks are TIG-welded for strong, reliable connections, ensuring no leaks under pressure. This is a manual transmission specific unit, so it does not include provisions for an automatic transmission cooler. Installation is intended to be a direct bolt-on process, utilizing the factory mounting points and connections, though you should always refer to the manufacturer's installation instructions for specific details.

When you're upgrading your BMW's cooling system, especially with a performance-oriented radiator like this, it's a good idea to also consider replacing your coolant hoses and thermostat if they are original. This ensures the entire system is in top condition to handle the increased cooling demands. This do88 radiator is a solid option for enthusiasts looking to improve their BMW's thermal management.
