Yup guys sure have had different luck than me. I ordered 6 coil packs for a Santa Fe, to which their website stated two different part numbers, and on different brands, as well. The difference being the back 3 coils had a three wire plug, and the front 3 had a two wire plug. So I ordered as directed. My vehicle had 2 wire coils on all six. So I tried to refund the 3 and order three of the two wire. I had to pay return shipping and restock before they would refund me. Haven’t used them since.
