Do you have your owner's manual? It has lots of interesting detail, and doesn't take long to run through it.

Thanks for the Info. Unfortunately I dont have an owner manual for my car. I did find the information in a service manual in the net but the AC 44 are hard to find here in Europe and I was thinking that there are some replaceables out there in the market. I found somewhere that AC Delco R44XLS may fit but not sure.
