Summary

This is a plug boot retainer for MSD spark plug boots. May work with other boots. Fits good but I have not field tested this design yet. I originally modeled it after MSD's design but I found it too flimsy so I added more material to make is stronger. You should run it with a zip tie to secure it. Printed with petg so it should hold up the heat. I printed this with a .6 nozzle solid infill and I used support.
