- 200–9000 rpm Bench Setting
- Digital Speed Display
- Height-Adjustable Plug Sockets
- Transparent Protective Cover
Key Features
Five Visible Positions with LCD Speed Control
1 Reference + 4 Test Plugs
Test up to five spark plugs at the same time. Use one standard spark plug and compare the remaining test plugs for clearer performance judgment.
Digital RPM Display
The LCD digital backlit screen displays the simulated speed setting, helping users adjust and observe test conditions more precisely.
200-9000 RPM Simulation
The tester simulates engine speed from 200 to 9000 rpm. The setting changes bench firing rate for comparison at a common setting; it does not prove spark strength under cylinder pressure or load.
Adjustable Test Hole Height
The adjustable hole position height helps the SPT360 support testing of long spark plugs.
Safety Protection Cover
The transparent protective cover helps improve safety and allows users to observe spark behavior during testing.
Five-Plug Digital Comparison
SPT360 combines five test holes with digital RPM control and adjustable hole height for long spark plugs. Compare compatible automotive and motorcycle spark plugs at the same bench setting. Close the transparent cover before testing.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Service Workflow
Load the Reference Set and Compare Together
Insert Spark Plugs
Insert the standard spark plug into the standard test hole, then insert the spark plugs to be tested into the remaining test holes.
Connect Power
Plug the power adapter into the side power port on the tester. Confirm that the indicator light turns on.
Close The Cover
Close the transparent protective cover before testing to reduce exposure to high-voltage spark activity.
Start And Adjust RPM
Turn on the power switch and press the RPM “+” or “-” buttons to adjust the working frequency.
Compare Spark Performance
Compare firing continuity and visible consistency at the same selected bench frequency. Higher settings increase the firing rate for comparison.
Simple Operation
Insert the spark plugs, connect power, close the cover, turn on the switch, and adjust the working frequency with the RPM buttons.
Safe Use
Keep High-Voltage Testing Enclosed
Close The Protective Cover
Close the transparent protective cover before testing. Do not run the spark plug tester with the cover open.
Power Off Before Handling
Do not insert or remove spark plugs while the power supply is connected. Turn off the power first.
High Voltage Warning
During operation, spark plug voltage can reach tens of thousands of volts. Do not touch the spark plugs directly with bare hands.
Use A Safe Environment
Use the tester in a suitable dry environment. Avoid hot, humid, or non-ventilated storage conditions.
Inspect Connections
Regularly check parts that need tightening or connection. Tighten loose parts in time to keep the equipment safe.
Maintain The Circuit
Check the circuit section thoroughly during maintenance and replace aging wires or worn parts when needed.
Use the Results to Plan the Next Check
The tester compares spark behavior in air. Confirm any suspected fault with the applicable vehicle procedure.

Buyer Questions
Spark Plug Fit and Comparison Questions
What Is The AUTOOL SPT360 Used For?
SPT360 compares one reference plug with up to four removed test plugs in air while displaying an adjustable simulated-RPM setting. The setting represents the bench firing rate, not real engine speed or cylinder load.
How Many Spark Plugs Can SPT360 Test At The Same Time?
SPT360 has five test holes and can compare up to five spark plugs at the same time. For a clearer comparison, place a known standard spark plug in the reference position and the plugs being checked in the remaining positions, keeping plug fit and the displayed setting consistent.
What Simulated-RPM Setting Does SPT360 Support?
The manual and specification table list 200–9000 rpm. This is an adjustable bench firing-rate label; compare plugs at the same setting and do not interpret it as real engine speed, pressure or load.
Does SPT360 Support Long Spark Plug Testing?
Yes. SPT360 supports adjustable test hole position height and is suitable for testing long spark plugs.
How Do I Use The SPT360 Spark Plug Tester?
Insert the standard spark plug into the standard test hole and insert the spark plugs to be tested into the other holes. Connect the power adapter, close the protective cover, turn on the power switch, and use the RPM “+” and “-” buttons to adjust the working frequency.
What Power Input Does SPT360 Need?
SPT360 uses AC 110V / 220V ±10% input power. Confirm the correct voltage version and power adapter before use.
What Safety Rules Should I Follow Before Testing?
Close the protective cover before testing, keep hands away from the plug and socket, and switch power off before inserting or removing plugs. The tester produces high voltage during operation.
What Is The Difference Between SPT101, SPT105, SPT301, And SPT360?
- SPT101 and SPT105 are two-hole 0-6000 rpm testers.
- SPT105 adds adjustable height and long spark plug support.
- SPT301 has three test holes, 200-9000 rpm, LCD display, and long spark plug support.
- SPT360 has five test holes, 200-9000 rpm, LCD display, adjustable height, and long spark plug support.

A+ tool. Fast shipping!
Arrived in 3 days. Box was slightly dented but the tester inside was perfectly fine. Hooked it up immediately to test some fouled plugs from my old Chevy. You can clearly see the spark jumping sideways to the ceramic on the bad ones. Good seller, solid tool. 5 stars.
