Does anyone know the model # of the Interstate Megatron Battery specific to our cars?

I read though the search forums and sounded like a sound choice, I was looking into the Optima, but saw too many negative comments/

thanks

Group 48 will work just fine. I can get the interstate # off a battery in the morning when i get to teh shop.

I use a Interstate MTP-91. Which is also the battery for pretty much all the other Porsche Sports cars. Uses the factory hold downs, and works great. I've had mine for about a year now.

No doubt Interstate are very good. I've had great results with SEARS Diehard, also.

Here in Europe I use MOLL, the factory OE supplier.
