Why is Automotive Spark Plug Tester Needed?
The function of the spark plug is to introduce tens of millions of volts of high-voltage electricity into the combustion chamber, and generate an electric spark to ignite the mixture, and cooperate with the ignition system and the fuel supply system to make the engine work. If the spark plug fails, it will cause the engine to fail to run because it cannot be ignited, and then cause the car to "lack of cylinders". The poor performance of spark plugs in the driving is manifested as: weak action, insufficient acceleration; unstable driving, poor refrigeration of air conditioner; increased fuel consumption, black smoke and so on. Generally speaking, spark plugs need regular inspection and timely replacement.
The automotive spark plug tester is a device specially used to safely and quickly detect the performance and quality of spark plugs. It replaces the traditional on-board spark test and is a professional and practical new device for testing spark plugs. The user only needs to place the spark plug on the tester, and after the tester generates high-performance and stable ignition high pressure, so that the spark plug will have a continuous flashover, the user can observe and compare the spark plug flashover strength and quickly judge whether the spark plug is good or bad. During the whole test process, the user can clearly understand the working condition of the spark plug, which is convenient for subsequent precise maintenance or replacement of the spark plug.
Why Choose AUTOOL SPT101 Automotive Spark Plug Tester?
AUTOOL SPT101 Automotive Spark Plug Tester is a professional and reliable spark plug testing device launched to meet the needs of the automotive aftermarket. It can be used to test the performance of spark plugs safely and quickly. SPT101 can simulate the working conditions of the actual engine, and has the advantages of simple structure, convenient use, large output energy, durability, etc.
Simultaneous Testing of Two Holes
Double hole test can be carried out at the same time. Two spark plugs can be tested and observed at the same time. It is convenient for users to make accurate judgments and take targeted treatment methods for spark plugs with poor working conditions through comparative tests. It is professional, reliable, efficient and time-saving.
Adjustable Working Frequency
The working frequency is designed to be adjustable from 0 to 6000rpm. The higher the frequency, the higher the strength of the spark plug. Users can make specific adjustments as needed to support flexible operation.
Protective Cover Design
In the process of spark plug testing, the working voltage can be as high as thousands of volts, there is a great security risk. SPT101 is equipped with a protective cover device. Covering the protective cover before use can effectively prevent accidental contact, ensure the operation safety of operators during the test, and avoid personal injury.
Built-in Indicator Light
The product is equipped with work indicator light and power indicator light, which can display the status of spark plug test more intuitively, and facilitate real-time monitoring of whether the test is running normally.
Easy to Operate
1. Put the spark plug in the test hole;
2. Close the protective cover;
3. Connect the power supply and adjust the working frequency;
4. Observe the test status of the spark plug through the protective cover.

I bought this simple spark plug tester to troubleshoot why the engine in my car isn’t starting. Well two of my plugs are totally dead and the 3rd plug is on its way out, with the 4th and remaining plug working just fine. Now I know why my car keeps cranking but not starting.

This is a hi-valu item for the home self-DIY person's home garage in changing their vehicle spark plugs for 'goodness' and 'spark gap'. Yes, I know the MFG says the plugs you have purchased are PRE-GAPed set and 'get it done' and drive, but the purchaser 'does not know' the plugs were miss handled and dropped on its ends between the time of MFG to their hands. The 'AuTool' spark tester is a very good device to settle any ? about the new items, one is to install in their vehicles, from lawn mowers to any new 16 plug Hemi. 032325. : )

Great diagnostic tool. If you need to test small engine plugs take a spare spark plug terminal and cut the part that wraps around the wire off. This gives you the extra length needed for the plug to make contact. Just wear gloves to remove the terminal. It gets sharp!

Was referred by a YouTube channel, "Chickanic". Had only a few days, my son had a friend who was having trouble with a plug fouling issue, he didn't suspect spark plugs because he had just put new plugs in it. My son asked for a spark tester, I suggested he try out this spark plug tester, "just for the fun of it", my son suggested they try out the tester. Turns out the fouling plug was not sparking correctly, even after cleaning. The new plug was bad out of the box. This tester saved diagnostic time verifying a bad plug. Very pleased with it and the reasonable cost.

I run a motorcycle shop, and I've always just had to use the ignition system of the bike I'm working on to test a plug. If a customer questions a plug I've replaced, it's really lame to do that kind of test as proof.This unit is amazing. I can test either one or two plugs at a time in either socket.I LOVE that kind of versatility.I find that a fouled plug will show its short on the lowest setting of this unit. The faster/stronger the spark, and the longer it sparks, will help the plug to spark in that same spot each time, so the foul condition appears less. Therefore, when testing a plug for foul/short/cracked ceramic/etc, always keep it on the lowest setting for the shortest time possible.A plug should never spark outside of its gap, so if a plug is observed to send a rando lightning anywhere else a single one time, that's all that's needed to condemn the plug.Then, I can prove(if needed) why the plug's bad using this fancy unit that tucks away so neatly! The power block completely fits into the clear cover, too. That might have been my favorite part!The manual is as simple as the unit, and also as complete as it could be. The quality of the packaging, manual, and certificate of conformity card is as impressive as the stringent quality control they put these units through(HIGH).Overall, I'm so very happy with this, especially at this price. 100% all around. I don't get to say that very often.
