SVT CT....any of those will work because they are all 3.5 inch flange...which is the same as the bat/mirko/etc maf adapter
Some people want a higher flow filter...the 3130 flows almost around the rate of the kkm....
If you have an svt I would go one of the ones I mentioned,
Might rub the hood a lil cuz its a big filter
