Should I go with OEM or Bosch +4's spakr plugs?

Any suggestion here...
And also do I really need to replace disks at the same time i change my brake pads?
I already had 2 sets of pads running on one set of disks.

BMW recommends you swap out the rotors on every brake change. They are pretty thin compared to rotors that can be cut between pads.

Go with the OEM NGK plugs as well, why screw with it if it works good.

If you have no brake pulsation and they`re above min. thickness I see no reason to replace rotors, your prior experience proves that it`s not ALWAYS required. Wonder how many sets have been trashed unnecessarily. BMW recommending replacement is not exactly an unbiased opinion. my .02

I suggest go with the OEM NGK's too. If you really want Bosch, go with the OEM Bosch, which were certified after the NGK's. The NGK are 4 electrode plug, the Bosch should be too.

As for brake discs, I believe min thickness is 20.4 mm (front discs). Check your your brake disc thickness and see what amount has been 'consumed' by the current set of pads. Then extrapolate it to see if you will exceed the min thickness with the new set of pads.

Edit: Just noticed that you stated that you have used 2 sets of pads, I think you are pushing it to try for 3 sets of pads.
