Looked it up. It is the TFI upgrade, bolt on dist cap adapter, upgraded cap & rotor,upgraded plug wires & updated coil. By TeamRush Anyone who's done the Motorcraft switch... - Jeep Wrangler Forum
Read #3 & # 12 (for pictures)
Would this work on a four banger 94 yj?
The TFI ignition upgrade replaces the small distributor cap and coil with an improved distributor cap, better wires, and a better coil. It made a huge different in my old 4.2 CJ7 - a very good upgrade.
The pictures you linked to are not a TFI upgrade (that teamrush pioneered), but are instead a GM HEI setup. That is said to provide at least as much improvement.
All this said, the part number aren't going to work for your 4 cylinder YJ. Everything researched for the TFI upgrade is for a 6.
