The CorkSport Advantage
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.
Fit & Finish
The 51r ECU Relocation Box is designed to use the OE mounting points for an easy installation with very little modification required to the wiring harness. The internal dimensions are designed around the industry standard 51r battery to fit all brands.
Materials & Manufacturing
CAD designed and manufactured from durable ABS plastic, the CorkSport 51r ECU Relocation box fits great and will stand up to the test of time. Battery restraint is completed with M6 studs and a 0.120" thick anodized aluminum plate.
