Exploring new manufacturing processes allowed us more flexibility in the design of the updated CorkSport ECU Relocation Battery Box. The new box features a 3-part design vs the old box and lid design. The additional component is designed with you, the customer, in mind.

The OEM battery box has a removal front panel to allow easy access and removal of the battery. The previous CorkSport ECU Relocation Battery Box did not have this feature and many of you made it very clear that that was an issue. We listened! Check it out below:

Just like OEM, the front panel is now removable! This drastically improves the access to the battery and the ECU. If you have ever had to change the battery in your Speed then you know the significance of the removable front panel. Here it is in action:
