30520-RAA-007 are the 04-05 ap2 coil packs as well as for a variety of other models, they were replaced by 30520-RRA-007 does anyone know the difference between these? I'm guessing they work on all pre DBW s2k's, but just want to make sure.

 

I'm not sure what the difference is except for the price, they all work so I would just get the cheapest ones.
