Because at one point I had a lean condition and my spark plugs were being destroyed over and over and I was talking to a few people that are mechanics who told me I might be better off for the time being to get AL 104's since they burned colder. Now that it isn't running lean, I could go and pay the ~$45 for the set of stock AC Delco's, but is it actually hurting the car to run the AL 104's?
