Tim H. –
This spark plug tester is the most suitable device I’ve purchased. Its dual-hole design improves efficiency, and the adjustable socket is compatible with both standard and extended luxury car plugs. No power source is needed—just connect to a battery. The data is clear and easy to read, and customer service responds very quickly. I would recommend this device if you need a spark plug tester.

Every time I have used it, it has worked correctly. It has identified spark plugs that are faulty even though they are new.
