Description

The Active Autowerke Rotrex C38 Level 3 Kit is a comprehensive forced induction system engineered for the BMW E9X M3. One notable owner, Mark Tarr, equipped his BMW E9x M3 with this 700 horsepower supercharger system and achieved dominant results in a performance sanctioned event, as documented with write-ups and videos. The kit aims to deliver substantial power gains, embodying Active Autowerke's "Come Play With Power" philosophy. This Level 3 kit utilizes the Rotrex C38 supercharger. While specific technical specifications for horsepower and torque are not detailed in the provided text, the owner's experience points to a significant increase, with one source mentioning over 500 HP and 480 ft-lbs of torque for a similar Gen 2 kit. It's important to note that this product is intended for off-road use only. Prior to shipment, customers must sign and return an Off Road Use Only Waiver, which can be emailed, faxed, or photographed and sent to the sales representative or info@activeautowerke.com.
