Perfect for the job saves time

Good quality, easy to work with, works great, bright light, like the longer boot for coil packs. Struggled with the shorter one in the beginning. I have the dreaded 5.4l 3 valve v8 F-150 and sparkplugs were just to start with....

Muy útil. Pará identificar fallos en cables y bujías. Y saber si hay chispa.

Great product and long plug to go down in the cylinder to connect to the spark plug and great to put onto the coils, long enough to see from cyclinder 1 and 8
