From reading here and finding out people say filters work better as they are used more, this one should be the one to go for first. Going to get efficient faster. The other common belief is the large pores fill first, so that means with the two ply media, they must put the fine mesh on the outside, because otherwise the large pore outer media would fill making a mess of it. The third thing I learned here is always listen to the owners manual if they say use a filter twice(my Chrysler manual says that). Then it follows since the manual knows it all, don't ever change the trans fluid if they say never change, lifetime fluid.
