Title says it all. Are the coil packs in the f20 the same as the f22?

 

you can use 04-05 ap2 coilpacks on an ap1, in fact some people report them to be an improved design over the ap1's, plus they are cheaper to purchase as they are also used on the RSX. You can use an ap1 coilpack on an 04-05 ap2 but apparently you might be going to a lower performing coilpack that way. I'm running the 04-05 ap2 coilpacks on my 2002 s2k. Do a search on part numbers, there are a few threads on this. You are not supposed to interchange 06+ ap2 coilpacks with earlier versions or use them on ap1's for some reason.
