Ford TFI from1986 to 1995 5.0L, about $20 to $50 at auto parts stores, buy pigtail connector there too $6. Many performance coils are that, with different colored housing and fancy heat sink mount.

do you have a part number for that one. the yr/make should suffice but parts house people do have (compentency) issues!
