Hi. Based on what I've seen on the forum, I'm shying away from them, and sticking with the OEM Bosch's. Check out the archives.
My experience on the seven has been OEM Bosch plugs. I will admit however, that I experimented with the platiums on my L6 with an M30 engine. The Platiums idled rough and the WR9LS (oem) plugs were far superior to the platiums. This issue has been kicked around a lot on the six series message board. Everybody agrees that original spec plugs are better than aftermarket marketing hype. In other words, Follow BMWs recommendations, after all, they should know best regarding their own car.
