RK Autowerks S63 Stage 2 Turbo Upgrade

The RK Stage 2 Turbo Upgrade is built for those who want serious power gains while keeping the drivability, spool, and reliability of the stock setup. Launch control remains fully functional with this upgrade.

To accommodate the larger internals, we CNC-machine OEM housings in-house using our 4-axis mill, preserving the factory bolt-on fitment and simplifying installation — no fabrication or adapters required.
