MSD Plug Seating Tool - Jalpa/Countach
by koihoshi
For owners who have installed MSD plug wires on their Jalpa or Countach, they will find it difficult to seat them due to how far down they go into the passageway. This tool is very simple and is roughly the diameter of the top of the boot and has an insert for 9mm plug wires. The tool simply slides over the wire, with the widest part on the bottom, and allows you to push down, centered, and seat the plug boot. You should hear the satisfying "click" or "pop" of the boot clipping over the end of the spark plug, and you're good to go.
