A failing TFI module is a classic cause of a hot-restart problem: the car runs fine until it heat soaks, then refuses to fire until it cools. This is the direct replacement module for Ford V8 TFI distributors, and it also fits OE TFI distributors, so it works as a repair part on a stock car as well as an aftermarket one.

MSD 83648 Ford TFI Replacement Ignition Module Features:

• Direct replacement for Ford TFI distributors, including OE units.
• Mounts on the distributor housing.
• Three terminal male connection.
• 12 volt operation.
