sounds like you probably have the stock 950 coil on your machine . the 300 coil is 12 inch , the d2 is the standard coil on the v3i , theres an eliptical 6x10 coil and a small eliptical 4x6 and there is also a 5.3 round mono coil.Originally Posted by emmarold1998 link=topic=4028.msg141765#msg141765 date=1369675270
