I put some in an 01 that I just started driving last week. I only bought them because they were on clearance at Wal-Mart for $3/pair. I didn't know what kind of problems the car had, so I didn't want to spend any more than I had to. After about 300 miles, these plugs seem just like the Champion 7034s that are in my other 2 M's. I will take them out of I decide to keep this car though, just because I'm not a huge fan of Bosch.
