I'm just highly confused on which plugs and coils to use I have a 2006 330i production date 5/05..... According to realoem ILZFR6D11 plugs and Bosch 12137594936 coil.....now I'm seeing people use the coil 12137594937 and ngk plugs plzfr6a11s...can u mix and match these??? What's the difference should I just get the 2 older or if I'm going to swap all out get 6 and 6 of the newer?
