AUTOOL SPT101 · DUAL-HOLE IGNITION SIMULATOR
AUTOOL SPT101 Dual-Hole Spark Plug Ignition Tester & Comparator
Simulate real-time engine speeds from 0 to 6000 RPM and compare a known-good reference plug against a suspect plug side by side under a protective transparent shield.
- 0-6000 RPM Adjustable
- Dual Test Holes
- Protective Safety Cover
Engineered for Professional Workshop Demands
The AUTOOL SPT101 is built to deliver speed, accuracy, and durability in busy service bays.
Dual-Hole Simultaneous Comparison
Insert a new reference plug in slot 1 and the suspect plug in slot 2 to visually compare spark intensity, color, and continuity at the exact same frequency.
0–6000 RPM Stepless Frequency Control
Turn the rotary knob from idle speed (1000 RPM) up to 6000 RPM to uncover high-speed misfires that never appear at low idle.
Transparent High-Voltage Safety Shield
Hinged impact-resistant clear cover protects technicians from high-voltage shock while offering a clear 360° view of the spark arc.
Industrial ABS Housing & Plug-and-Play
Oil-resistant insulated ABS body powered directly by the included 12V DC wall adapter for instant benchtop diagnostics.
COMPARATIVE DIAGNOSTICS
Distinguish Good and Faulty Spark Plugs in Seconds
Engine misfires, rough idling, and poor fuel economy are frequently caused by degraded spark plugs. Unlike single-hole testers, AUTOOL SPT101 drives two plugs simultaneously so you can immediately spot weak yellow sparks or ceramic side-tracking.
- Clear visual distinction between strong blue-purple arc and weak yellow spark
- Exposes high-RPM spark dropout above 4000 RPM
- Provides undeniable visual proof of worn plugs for workshop customers
REAL ENGINE SIMULATION
Precision Stepless Frequency Adjustment from 0 to 6000 RPM
Many degraded plugs fire normally at idle but fail under high engine load and speed. The rotary potentiometer increases firing frequency smoothly up to 6000 RPM right on your workbench.
- Smooth transition from 1000 RPM idle to 6000 RPM full-load simulation
- High-voltage indicator LED and audible spark frequency feedback
- Compatible with iridium, platinum, and standard nickel 12V spark plugs
MAXIMUM WORKSHOP SAFETY
Protective Clear Shield for Safe High-Voltage Testing
Ignition testing generates thousands of volts at the electrode tip. The transparent protective dome prevents accidental contact with high voltage while keeping acoustic noise and ozone contained.
- Full-enclosure transparent dome prevents electric shock
- Stable 12V 1A DC external power adapter included
- Compact 354g footprint with non-slip benchtop feet

Workshop Application & Operating Guide
Recommended 4-step standard operating procedure for accurate results.
Insert Spark Plugs into Test Holes
With the unit turned off, place a known-good reference plug into hole 1 and the suspect plug into hole 2.
Close the Transparent Safety Shield
Close the clear protective cover completely to isolate high voltage and connect the 12V power adapter.
Simulate 1000–6000 RPM Engine Speed
Turn the rotary switch clockwise to power on and gradually sweep the speed from 1000 RPM up to 6000 RPM.
Evaluate Spark Color and Continuity
A healthy plug produces a concentrated blue-purple continuous arc; scattered, yellowish, or intermittent sparks indicate replacement is needed.
Conventional Methods vs. Professional Diagnostics
How precision engineering eliminates guesswork and comebacks.
Conventional / Basic Methods
- Dangerous open-air grounding against the engine block
- Tests only at cranking speed (250–300 RPM)
- No side-by-side comparison with a reference plug
- High risk of electric shock or fuel vapor ignition
With AUTOOL SPT101
- Fully insulated high-voltage testing under a clear safety cover
- Full 0–6000 RPM road-load frequency simulation
- Simultaneous dual-hole comparison of new vs. old plugs
- Instant visual confirmation for technician and vehicle owner

Frequently Asked Questions
Key technical questions from technicians and workshops about the AUTOOL SPT101.
Which spark plugs are compatible with AUTOOL SPT101?
It is compatible with standard 12mm thread spark plugs (nickel, platinum, and iridium) used in 12V petrol passenger cars and motorcycles.
Why is a dual-hole tester better than a single-hole tester?
Comparing a used plug directly next to a brand-new plug at the exact same firing frequency makes weak sparks and gap erosion immediately obvious.
Why test up to 6000 RPM?
Worn plugs often fire adequately at idle (800–1000 RPM) but miss under high-RPM load. Testing up to 6000 RPM reveals hidden high-speed misfires.
Why must the transparent cover stay closed during testing?
The tester generates high voltage across the spark plug gap. Closing the cover prevents accidental electric shock.
What does a healthy spark look like?
A healthy spark plug produces a steady, concentrated blue-purple arc across the center electrode gap without side-tracking.
What warranty is included?
Backed by a 1-year official Otoeko distributor warranty with full technical support.
