I just bought an 04 MT RX8. I have done a little researxh and found nothing that would tell me if I have a 4 port or 6 port, or what the difference is. I know this is a stupid question, and I probably could have used the search button a little better, but oh well. Thanks for the help.

All 6 speed MT's are 6 port. As I recall, only the early AT's had the 4-port engine. Do some searches when you have questions and you will find a friendly forum.
