Why did I wait so long to buy one of these?
This device saves so much time trying to determine if a small engine has spark. It is so much easier than pulling the spark plug and trying to prop it up against the case of the engine to see if it has spark. Just hook this up inline to the spark plug, crank the engine, and get immediate feedback that spark is present. This is great.

Great item
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
