BMW will offer a factory N55 powerkit, power boost to about 320 horsepower + retaining warranty
We have learned that an N55 powerkit will be coming relatively soon from BMW for all models. What will it consist of? Well, it will be very similar to the N54 powerkit offering a slight bump in power and cooling upgrades. This will of course maintain the factory warranty and be available as an option during the order of the vehicle or to be installed at the dealer. The engine will go up to about 320 horsepower and 330 pound-feet of torque from the standard ratings of 300/300. Pricing and details to come when the official announcement is made.
