What is the difference with the above? I need 2x as I've got 6 cylinders to ignite and want the same ignitor across all banks - assuming there is some difference! Or are they all the same just different revisions or something?

Bosch Motorsport IM 3.2 has the standard part number xxx 203 so presumably that is the 'best'?

Or the there is also a 139 etc etc.

They are simply current versions, or layout configurations. In the table below, you see a single-connector version, and a two-connector version, for example. Keep in-mind, different versions can be for different use, e.g., sensor triggering instead of ECM triggering. Also consider, you can use too many channels and ignore some (two 4ch modules) or 3x2-ch, or 6x1-ch, etc.

Found this BTW for anyone trying to find the 'right' ignition module
