impreza ignition coil question

[jv.goff]

Hi All,

Is there a significant difference between the 22433AA360 coil pack and
the AA230 ? I have the AA230 with a hairline crack in the enamel, and
many parts websites i search show the 360 when i fill in the correct
year/model etc. Just wondering if they can be interchanged ??

car is a 94 impreza 1.8 2wd - any help / comments (or a cheap canadian
parts source) appreciated,

thanks
