Coil Packs

I looked through old threads but i could have missed something...I have an 2003 9-3 Arc and it has the individual coil packs, I see that there are the cassettes that have all 4 together molded from one piece of plastic, as opposed to mine how its individual for each spark plug.

My question is, do the cassettes fit the cars such as mine where are there single packs? probably a stupid question, but thought I would ask.

Thanks
