Dinan has just announced the new power upgrade for BMW M3 and M4. The U.S. tuner created a Stage 3 upgrade kit which fits both the M3 and the M4 and their Competition Package versions.
When using this kit, the cars are promised to reach 548 HP (573 HP for Competition Pack models) and 744 Nm of torque.
To get the maximum performance out of the 3.0-liter bi-turbo S55, a new cold intake, heat exchanger, and exhaust are required. Dinan promises that their new product, heat exchanger, helps gain 10 horsepower by itself.
The final product is a car from which you can get a lot more life and enjoy it at its fullest.
