Could someone let me know the part number for an Optima Red Top battery that best fits a 2012 Grand Sport A6 (engine compartment located). The Optima website does not have a spec for my car.

Thanks in advance

Autozone, Optima batteries are not car specific. But if look in each battery size group they give battery dimensions of battery.
