I'm not really sure to being honest. As far as I've heard and read on the forum the A model is the engine in the 320i and the B model the one in the 330i. If you're looking to tuning/optimize your car and look at some of the resellers you can often see "Only for the B48B20B engine" and therefore it's more desirable I guess.
