Product Comparison

Product Comparison

Compare SPT101, SPT105, SPT301, and SPT360 before choosing the right tester for test hole quantity, simulated RPM range, adjustable hole height, LCD display, long spark plug support, and workshop testing volume.

SPT101 FocusBasic dual-hole spark plug tester with 0-6000rpm simulation, adjustable simulated RPM, and a safety protection cover. It does not support adjustable hole position height, long spark plug testing, or LCD digital display.
SPT105 FocusDual-hole spark plug tester with 0-6000rpm simulation, adjustable test hole height, long spark plug support, and a safety protection cover. Choose it if you need long spark plug compatibility but do not need an LCD screen.
SPT301 FocusThree-hole spark plug tester with 200-9000rpm simulation, LCD digital backlit screen, adjustable hole position height, and long spark plug support.
SPT360 FocusFive-hole spark plug tester with 200-9000rpm simulation, LCD digital backlit screen, adjustable hole position height, and long spark plug support for higher-volume comparison testing.
Decision CheckChoose based on test hole quantity, RPM range, adjustable hole height, LCD display requirement, long spark plug support, and whether you need basic comparison testing or higher-volume workshop testing.

Key Features

Key Features

SPT105 is built for quick spark plug comparison, simulated RPM testing, long spark plug compatibility, and safer observation through a transparent protective cover.

Dual-Hole Comparison

Test two spark plugs at the same time to compare spark status more quickly during basic 12V vehicle spark plug checks.

Adjustable Test Hole Height

The adjustable height design improves compatibility with longer spark plug ends used by BMW, Volkswagen, Audi, and other models.

0-6000rpm Simulation

Adjust the simulated engine working speed from 0 to 6000 rpm to observe spark plug performance under different test conditions.

Visual Spark Observation

The tester helps users visually check ignition strength, spark continuity, and comparative working status through the transparent cover.

Protective Safety Cover

Close the protective cover before testing to reduce direct exposure to sparks and improve operational safety.

3-Year Support

AUTOOL provides 3-year warranty support for eligible non-human damage cases and product support for setup and compatibility questions.

How To Use

How To Use

SPT105 is simple to operate: place the spark plug, close the protective cover, connect power, adjust the working frequency, and observe the spark status through the cover.

Place Spark Plug

Place the spark plug securely into the test hole. Use the adjustable test height when testing longer spark plug ends.

Close Safety Cover

Close the transparent protective cover before starting the test to reduce direct spark exposure.

Connect Power And Adjust RPM

Connect the correct 110V / 220V power supply option, then adjust the working frequency or simulated RPM with the control knob.

Observe And Compare Spark Status

Observe the spark plug test status through the protective cover and compare performance if two plugs are tested together.

Use Notes

  • Close the protective cover before testing.
  • Confirm the correct 110V / 220V input option before connecting power.
  • Keep hands away from the test hole area during operation.
  • Use the adjustable height function for longer spark plug ends.

Before You Order And Use

Before You Order And Use

Confirm voltage option, display needs, long spark plug testing requirements, and operating safety before ordering or using the SPT105.

Confirm Input Voltage

Confirm the correct 110V / 220V input option before ordering or connecting power.

No LCD Display

SPT105 does not include an LCD digital backlit screen. Choose SPT301 or SPT360 if a digital display is required.

RPM Range Check

SPT105 supports 0-6000rpm simulation. Choose SPT301 or SPT360 if 200-9000rpm simulation is required.

Long Spark Plug Support

SPT105 supports adjustable test hole height for longer spark plug ends. SPT101 does not support this function.

Close Cover Before Testing

Always close the transparent protective cover before testing to reduce direct spark exposure.

Spark Plug Test Scope

    Works great! I shared it with my fellow mechanics, and they thought it was awesome! We compred a very worn plug to a brand new one, and the difference was quite obvious.
