RK Autowerks S63 Stage 2 Turbo Upgrade – M5 M6 M8 X5M X6M



In stock (can be backordered)


The RK Autowerks Stage 2 Turbo Upgrade is the perfect solution for those looking for more power while retaining stock drivability and turbo spool.  You are still able to use launch control with this setup.

To fit the larger turbos, we mill out the stock housings on our 4-axis CNC mill, right in our shop.  This retains the bolt on application for easy installation.
