About this item

  • 【Upgraded Test Hole—Knob Type】Compared with the fixed test holes of other spark plug testers, the upgraded knob-type test hole of this tester can be adjusted to meet the testing needs of more spark plugs, ensuring good contact and accurate testing between the spark plug and the tester.
  • 【Dual-hole Simultaneous Testing】Testing two spark plugs at the same time can quickly see their spark intensity, so as to determine which spark plug has problems or poor performance. It also reduces the time and operation steps of testing spark plugs one by one, greatly improving the efficiency of detection.
  • 【Power and High-Voltage Indicator Lights】The power indicator light intuitively indicates whether the spark plug tester is powered on. When the spark tester generates high voltage electricity and applies it to the spark plug, the high-voltage indicator light will light up, reminding the operator to be vigilant during the test and avoid contact with the high-voltage part.
  • 【Protective Cover Design】The protective cover can effectively isolate the high-voltage area and provide a safety barrier for the operator. The protective cover can also prevent dust and moisture from entering the interior of the spark plug tester to avoid affecting the test results.
  • 【Easy To Operate】Insert the spark plug into the test hole, cover the protective cover, plug in the power adapter, and adjust the working frequency. The higher the frequency, the higher the spark plug strength.

This is an excellent tool for anyone who works on cars, motorcycles, or engines in general. I have a rather large stockpile of spark plugs that I've gathered through the years (Vintage, New Old Stock, and brand new) and this tool takes a lot of guesswork out of things when you want to see if a spark plug is any good before you use it in an engine.The tester works very well and is a great value for the money!
