Xbimmers is a subforum of other countless subforums, which all seem to operate together across various BMW models because I'm not asked to sign in each time I'm on a 3 series, 5 series, etc forum. Feel free to search my screen name as I've been replying on countless other threads, but long story short is that these injectors used across multiple platforms and the 3 series guys have had great luck using brand new SMP injectors purchased through Rockauto, which after a 5% discount would be just over $900 for all 8, then apparently each decoupler needs to be replaced at the same time, which are about $8 a piece. I've also searched on eBay and have found two sellers, which combined, will sell 8 used index 11 injectors @ $35 a piece. Used injectors means new gaskets at the tip @ $3 each, the same decouplers and then no matter who you purchase your injectors through, they need to be coded through NCSExpert, which you'll read about on the 3 series forums using a tool and software that's about $100.
