Because not everyone can afford the $1300+ for six of the new version, even if it is a little better. The reason BMW replaced them has nothing to do with the N54 engine. It's because the N63 (V8) engine had issues with the older version and it's simply easier to produce and stock one product compatible across multiple product lines then a version specific to just the N63. I bought one of the old version from Tischer/BMW of Silver Spring as a spare just in case I need to replace one down the road. If I have to replace more than that I'll bite the bullet and replace all six.
