When swapping the ECU or shaving the bay, the oem plastic ecu shroud (OEM PN: 12521735108) is no longer usable nor attractive. Without some cover the ecu bin fills with moisture, debris and is exposed to additional heat. 
 
We had made these  cover plates to help improve the bay while protecting the ecu!
 
They are manufactured out of thick 11 gauge stainless (1/8") with a brushed finish. They mount using oem locations. The plate has a large blank which can be modified to use a grommet to pass the harness through or seal the compartment entirely.
