Questions about this product

Will this tester work on my motorcycle or lawnmower, or is it just for cars?
It works on any gasoline engine with standard ignition systems. The double-hole design fits standard 14mm and 18mm spark plug sizes. This makes it perfect for cars, motorcycles, and small engines. Just ensure you connect it to a 12V DC power source.
Can I use this tester to simulate high-speed engine conditions?
Yes, you can test ignition performance from idle all the way up to 6000 RPM. It safely withstands up to 40kV of maximum voltage. This wide range lets you easily spot intermittent misfires that only happen at higher speeds.
Why does this diagnostic tool have two holes instead of one?
The double-hole design lets you compare a new spark plug against your old one side-by-side. You can visually check the spark strength and consistency of both plugs at the same time. This makes it much easier to isolate a weak plug or a failing ignition coil.
