Perfect for the job saves time
A**.
Bottom line up front, if you're considering buying an inline spark (plug) tester, I highly recommend buying the Lisle version. Sure, you'll spend a bit more on it. For me, it was a "one time use" purchase however this was my *second* purchase because I bought another much cheaper brand the was broken upon arrival. In short, I didn't save any money buying the more affordable version. This Lisle tool is as all others have said, a very solid product with a bulb you can actual find and replace. It is well made, durable and will last for many years of use I'm sure.

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
