Ours were replaced at 4 years under the free maintenance program, with <30k miles.

I think it should be changed at around 50k-60k

IIRC, there were few different NGK plugs used in the n20 BMWs. The earlier generation of NGKs required more frequent changes. Then later versions didn't need to be changed as frequent. Something like every 60k miles or something as opposed to every other oil change. There was a thread around this here.

BMW says 60k miles. Bentley manual and Otto from BavAuto recommend 30k miles.
