My Ride: BMWs & MINIs
While the box is incredibly similar, BMW claims it is reworked and provides a very modest 3hp gain (some dyno testing indicated a 6.5 - 8 HP gain). That coupled with the Carbon Fiber accent, and increased sound from 4k - 5k RPM made it a popular item when pricing was below the $1,000 MSRP.
