I think the Star requirement might be triggered by age of the vehicle. I have needed a star facility since my 2012 test. I had to remove my XL brake booster canister and my WAI. They let me keep the grill blocking, but I maybe should have removed it for the sake of engine heat and higher possible NOx readings. I cleaned and gapped the OEM spark plugs and swapped them in before the test.
