Just looked up one for my Olds on the O'Reilly website, and it's still Wix. Still using the same Wix part numbers. Just has MGL before the Wix part number.
Look up the Wix part number, and then compare it to the MicroGard part number.
Also, NAPA Gold is Wix. NAPA ProSelect is probably similar to the MicroGard which equals Wix ProTec a jobber filter.
