2001 Dodge Stratus spark plugs

I had the wrong spark plugs put in my car by Mr. Tire, and had to go to a dodge dealership and pay them to fix the problem. What kind of spark plugs are suppose to go into my car. I am asking so that I can go back to Mr. Tire and tell them that they put the wrong plugs in my care and get my money back. The plugs they put in were NGK Ridium/BKR6EIX-11 and NGK Ridium/BKR5EIX-11.
