BITURBOX is a complete and plug and play replacement for the inner workings and fuses of the fuse box (Maserati part No. 313020104) used in all the Maserati Biturbo family cars, from 1981 to 1994. Biturbo to Shamal, we got them all covered, except the ABS versions. Say goodbye to the electric gremlins and enjoy your classic Maserati the way it should be!
