I added a couple $9 brass adapters and solved the errors on wife's 3.0 about 25 months ago no errors since.
I'm not having any drivability issues, but the code is:
"Catalyst System Efficiency below threshold"

I don't think the spacers will fly here as they inspect under the car with mirrors when you go for inspection, even though they do a plug-in to the OBD.
