B/A and Fel Pro are both owned by Federal Mogul. Let us know if the gaskets are the same. Sometimes the B/A parts are sourced from OE/OEM vendors.
Not sure which yr your RDX is, but the 16/17 RDX use a different part number than what you have listed.I don't want to fight with the wiring harness in a few years so I order these oem today for the MDX and use Felpro Cover Grommets as well. Will use the beautiful blue gasket for the Accord. Will store the extra set of oem gaskets for the RDX.

Edit: if you remove the harness bolt (the one that attaches to the Mount bracket), the harness is more manageable.
