BMW 1M comes from the factory with an auxiliary radiator smaller than a half sheet of paper. It will do little to keep the "limp mode" or heat soak away during a track day.

The Dinan® High Capacity Oil Cooler provides literally twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that\\\\'s really just the beginning. Nicely integrated inlet ducting provides greater airflow efficiencies and the ventilation of air to the fender well has also been improved with a larger outlet. The system mounts neatly in the stock location and includes lightweight convoluted PTFE hoses with polyester outer braid fitted with race-quality fittings.

Specifications Total Volume Stock: 9.5 oz. / Total Volume Dinan: 19 oz.
Stock Surface Area: 45 sq./in. / Dinan Surface Area: 67.5 sq./in.
Stock Cooling Tubes: 10 / Dinan Cooling Tubes: 23
Stock Tube Length: 90 in. / Dinan Tube Length: 207 in.
Stock Tube Area: 112.5 sq./in. / Dinan Tube Area: 414 sq./in.

The results of the oil cooler upgrade are quite significant, with the temperature gauge holding steady even under high load/high boost scenarios. And for those of you who track their cars, even occasionally, the Dinan® oil cooler is a must.

Performance Engine Software (D900-30®, D900-30TMC): Dinan® Stage 2 Performance Engine Software safely increases turbo-boost pressure, along with properly retuned fuel mixtures, ignition timing and full map rescaling for your BMW 1M E82. Dinan’s software also removes the top speed governor so the BMW will be capable of achieving its natural top speed. Producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product. In an effort to more effectively control oil and water temperatures, the Dinan software actually increases water pump speeds as boost pressure increases. And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.

High Performance Intercooler (D330-0010B): Greater power gains are achieved with a larger high performance intercooler. The Dinan® intercooler offers double the volume of the stock unit, substantially reducing the pressure drop by 0.7 psi, as well as providing more efficient heat exchange. "Cool down" time is also reduced, enabling the cars to produce full power under varying driving conditions such as stop and go traffic. The system has been engineered as a direct replacement for the stock unit, requiring only minor modifications for a clean, factory-like installation. The intercooler also features larger connector tubing and custom shrouding for maximum efficiency.
