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

This do88 radiator features a core thickness of 42mm, which is 10mm thicker than the stock BMW unit. This increased thickness, combined with a high-density fin design, allows for significantly improved cooling capacity. It's built to handle the demands of the N54 and N55 engines found in the 2007-2013 BMW 135i and 335i models, specifically for automatic transmission vehicles.

Constructed with all-aluminum tanks and a brazed core, this radiator is well-built for durability and efficient heat transfer. The all-aluminum construction helps reduce weight compared to stock radiators that might use plastic end tanks. The brazed core ensures a strong, leak-free connection between the tubes and fins, which is crucial for maintaining consistent coolant flow and preventing failures under pressure. This design is intended to keep your engine running cooler, especially during spirited driving or in warmer climates.

This radiator is designed as a direct replacement for your original unit, meaning it fits right into the factory mounting locations. It's a solid option if you're looking to upgrade your cooling system to better manage engine temperatures, whether you're dealing with track use, heavy loads, or simply want the peace of mind that comes with improved thermal management for your N54 or N55 engine.
