High Capacity Oil Cooler System

The Dinan High Capacity Oil Cooler System addresses the tendency for BMW 335i models, particularly those driven spiritedly or with increased boost pressure, to run excessively warm. It provides double the volume of the stock unit and boasts 414 sq./in. of cooling tube surface area, compared to the stock's 112.5 sq./in. The system integrates smoothly into the stock mounting location and utilizes lightweight PTFE hoses with a polyester outer braid and race-quality fittings. The design also incorporates enhanced airflow with integrated inlet ducting and improved ventilation to the fender well through a larger outlet. The results show the temperature gauge holding steady even under high load and high boost conditions, making it essential for track-day enthusiasts or aggressive drivers. Key features include: - Total Volume: 19 oz. (Dinan) vs. 9.5 oz. (Stock) - Surface Area: 67.5 sq./in. (Dinan) vs. 45 sq./in. (Stock) - Cooling Tubes: 23 (Dinan) vs. 10 (Stock) - Tube Length: 207 in. (Dinan) vs. 90 in. (Stock) - Tube Area: 414 sq./in. (Dinan) vs. 112.5 sq./in. (Stock) This oil cooler system is specifically designed for 2007-2010 BMW 335i E92/E93 models that do not have a factory oil cooler. It is not compatible with vehicles equipped with the M-Technic bumper.
