|This popular Spark Plug Cleaner & Tester now works with both 120V and 220V sources, and has advanced circuitry to prevent thermal overload during heavy use. Itís smart, functional styling combined with rugged construction makes it the perfect choice for anyone who needs to reliably and accurately check the quality of used spark plugs. The cleaner section uses a powerful blast of air and abrasive to thoroughly remove carbon deposits from plugs. The recessed observation mirror is perfectly angled to display the electrodes of the spark plug so that you can clearly judge the quality of the spark as the plug is being tested. It is manufactured to the rigorous ISO 9002 standard and carries a full one-year warranty.|
I like this unit, I have always used the Champion one at my Sons business and I think this one does the same job. If can make two comments, one is the air fitting, it is not very accessible or easy to change. Second it does not seem to have the same spark power as the Champion. It may just be me, I can not compare them side to side.
The only way to clean and test plugs. I've used one in my shop for 30 years.
