Product Description
A package of ten, 45-degree, 3D-printed, spark plug boots.
When cutting the boot from the tree, a stem remains to insert into the head's spark plug hole (use a #70 drill bit).
The hollow end accepts Pro Tech's Spark Plug Wire. Pro Tech recommends drilling the boot hole with a #74 drill bit (see their instructions on the back of the header card).
3D-printed, by Pro Tech, 1/25 scale.
