As boost is increased through the use of performance software, the single factory intake becomes restrictive and the engine is lacking the air it needs to make maximum power. The new Dinan cold air intake force feeds the 1 M’s 3 liter turbocharged inline 6 with greater volumes of cool, oxygen rich air for substantial power gains by utilizing our secondary carbon fiber intake. The system is so effective that the carbon fiber inlet air temperature is a full 40 degrees Fahrenheit cooler than the incoming air from the stock inlet. Due to the increased airflow from our intake, the power-curve is extended into the higher RPM’s for a noticeable change. The system is a direct replacement for the factory air box lid, employing a hand-crafted carbon fiber unit that also includes a secondary carbon fiber intake tube that captures cool air from the lower grill and includes the shielding for the conical filter to insulate it from power robbing engine compartment heat.

The new 1 M Stage 3 Performance Engine Software safely increases turbo-boost pressure and is optimized to take full advantage of the Dinan High Performance Intercooler. With a peak horsepower of 398 at 5700 rpm and peak torque of 429 lb-ft at 4300 rpm as tested with the Dinan High Capacity Oil Cooler System and Dinan Free Flow Exhaust, this package makes for a monumental increase in power over the stock 335 horsepower and 370 (with overboost) lb-ft of torque BMW quotes. There is more to the Dinan Stage 3 Software than just cranking up the boost however. Refinement and driveablility are both fully maintained as power comes on smoothly and predictably which makes the 1 M as fun to drive at wide open throttle as while cruising around town. In addition, boost is tapered at higher levels to keep from over heating and damaging the turbos.

Greater power gains are achieved with the new 1 M Dinan larger high performance intercooler. The Dinan intercooler provides a 93% increase in total volume, 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 car 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.The improved thermal efficiency will also enhance turbocharger reliability. The new 1 M intercooler may also be used in conjunction with the Dinan oil cooler and Stage 3 Engine Software with increased boost pressure to take advantage of the improved intercooler efficiency.

The new Dinan 1 M High Capacity Oil Cooler provides twice the volume of the stock unit, as well as 414 sq./in. of cooling tube vs. 112.5, and that’s just the beginning. A 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 PTFE polyester braided hoses and race-quality fittings. 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. For those who track their cars, even occasionally, the Dinan oil cooler is a must.

The Dinan 1 M Monoball Kit provides responsiveness you can feel by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Responsiveness is further improved by eliminating the deflection inherent in the stock rubber bushings while also reducing brake shimmy. The quietest bearings on the market are virtually noise free so you can live with them everyday. These are the only bearings on the market that are sealed using a rubber boot to keep out dirt and road grime, thus preventing premature wear.
