iwp189, with the pink band and std in 1098, 1198, 848(?), is nominally a 12 hole version of the iwp069 with the yellow band, which is std in 748r, 749, 998 and 999.  i think the s4rs has the 189.

in a dynamic test they do flow more than the 069, about 12% according to doug from memory.

i have been told they are a good retro fitment to a 749, 999, etc in terms of general running.  but they should make it run richer.
