All retail battery providers can tell you the proper battery code. Just go there and get one.

Here is what Interstate comes up with for your/our cars: http://www.interstatebatteries.com/e...CRank%7C1&js=1

I just put this one in mine (I did however move the battery under the right rear seat):

I had the previous Interstate battery MTP-93 for 7+ years before it would no longer hold a charge. $118.00 installed including new vent tube.

take a ruler and measure the length. tell us what it is, and we can tell you if you can use a group 49. which seems to be the best deal going as far as "power" goes, and is what most e34s use.
