The last time I went to the dealer just to see what they charged, $25ea sounds outrageous for the 540. I've used bosch plugs before and they had the tendency of backing out. Had really good luck with the NGK's. I've already done plugs on the X after the wife and I bought it. Had 78k in march and now at 94K. Probably change around 100-110K, but may go a little longer since the X's plugs cost more.
M cars use different plugs than the X. That's why M5 guys do it more often. The X should be good for 80K-100K per what FSETH said. 30K for plugs is way overkill on the X5...just like guys that like to change oil every 3K-5K on the X.
