Performance Advantage

Designed to work with up to 4" intake systems, the 51r ECU Relocation Box provides approximately an extra 0.75" of clearance (compared to the full-size CorkSport Battery box) without sacrificing fit and finish.

The ECU is relocated to the driver's side of the battery box with the wiring harness routed inside the box for a clean and purposeful look. The single lid design provides easy and ample access to the battery and ECU.
