Correct. Either Eddy RPM air gap, or Chinese knock off air gap. Mopar performance made a nice dual plane (non air gap) and a single plane, but they messed up by making them too early, meaning magnums were fairly new and nobody was swapping them into older vehicles. Mopar got out as sells were down, so we have our two choices - unless you drill :) I asked Johnny Mac to make a nice dual plane (non air gap) that sells for 200 bucks, and it would go. More magnum swaps than ever, and not everyone wants a air gap
