PRECISION SPARK PLUG GAP TOOL

SET THE GAP.
MEASURE IT.
KNOW IT'S
RIGHT.

A CNC aluminum spark-plug gap setter paired with a 32-blade thickness gauge—giving you one controlled workflow for adjusting and checking compatible spark plugs before installation.

🔧 Controlled Adjustment 📏 32-Blade Gauge ⚙️ CNC Aluminum Body 🚗 Garage Maintenance

LESS BENDING BY FEEL

Turn The Knob.
Move The Electrode
Gradually.

Seat a compatible spark plug in the tool and use the threaded adjustment knob to make smaller, more deliberate changes to the ground electrode.

🎯 Controlled Pressure

The screw-style mechanism makes gradual adjustment easier than rough hand bending.

🔄 Smooth Adjustment Knob

Turn the knurled top control progressively instead of forcing the electrode at once.

🧠 Adjust With A Target

Work toward the actual specification rather than relying on visual guesswork.

BUILT AROUND ONE PRECISE JOB

CNC Aluminum.
Smooth Knob.
Purpose-Built Groove.

The current product imagery identifies a CNC aluminum body with a shaped spark-plug groove and a screw-driven adjustment block.

⚙️ CNC Aluminum Body

Current product graphics specifically identify the tool body as CNC aluminum.

🔩 Precision Groove

Shaped channels position compatible spark plugs during adjustment.

🖐️ Knurled Control

Textured knob gives your fingers a more deliberate adjustment surface.

MEASURE • ADJUST • RECHECK

The Gauge Is
Part Of The Process.

The setter changes the gap. The thickness gauge checks it. Using both is what turns the process from “that looks about right” into a measured setup.

1 Find The Required Gap

Confirm the correct specification for your exact engine and spark plug.

2 Adjust Gradually

Turn the knob carefully to change the electrode position in small increments.

3 Measure Again

Use the included thickness gauge and confirm before installation.

32-BLADE THICKNESS GAUGE INCLUDED

Don't Stop
After Turning
The Knob.

The current product package shows a folding 32-blade thickness gauge for checking the gap after each adjustment.

3️⃣2️⃣ 32 Blades

Multiple marked leaves provide different thickness references.

📐 Inch & Millimeter Markings

The current gauge chart presents thickness values in both measurement systems.

🔁 Easy Rechecking

Measure again after every adjustment rather than assuming the setting is correct.

CHECK YOUR PLUG BEFORE ORDERING

Four Thread Sizes.
Four Reach Profiles
Shown.

Current compatibility imagery identifies four spark-plug thread sizes and four spark-plug reach dimensions.

COMPATIBILITY IS MORE THAN THREAD DIAMETER Confirm your actual spark plug dimensions and design before use. The listed sizes describe the current seller compatibility graphic rather than a guarantee for every spark plug within those nominal dimensions.
COMPACT WORKBENCH SIZE

Small Enough
For The
Tool Drawer.

The current dimension graphic shows a compact body designed to stay easy to store alongside sockets, gauges and routine ignition-service tools.

4.8" Main Body Length

1.3" Body Width

Approximate width shown in current dimensional artwork.

1" Body Height

Main aluminum body height shown before the upper adjustment assembly.

GARAGE READY

For Routine
Spark-Plug
Service.

The simple mechanical setup makes the tool useful for DIY garages and maintenance workflows where compatible spark plugs need to be checked and adjusted.

🏠 DIY Garage

Add a dedicated gap-setting step to home spark-plug maintenance.

🔧 Routine Service

Useful when preparing compatible replacement plugs before installation.

🧰 Toolbox Friendly

Compact dimensions keep the setter and gauge easy to store together.

PRECISION IS A PROCESS

Adjust.
Measure.
Confirm.

One knob turn should never be treated as proof that the gap is correct. Use the gauge, check the actual clearance and repeat carefully if needed.

DO NOT FORCE THE ELECTRODE Make gradual adjustments and follow the spark-plug manufacturer's guidance. Some modern plugs and electrode designs may require special handling or may not be intended for conventional gap adjustment.
WHAT IT REALLY SELLS

Not More Force.
A Better
Adjustment Routine.

The advantage is pairing a controlled mechanical setter with an actual measuring gauge. Instead of bend-and-guess, you can work through the same sequence every time: specification, adjustment, measurement, verification.

🎯 Control

Move the electrode gradually through a screw-driven mechanism.

📏 Measurement

Included 32-blade gauge lets you verify rather than visually estimate.

🔁 Repeatability

Follow the same measured workflow across compatible spark plugs.

PRODUCT HIGHLIGHTS

Adjust The Gap With
Control—Then Measure It.

🔧 Dedicated Spark-Plug Gap Setter

Purpose-built for controlled ground-electrode gap adjustment.

⚙️ CNC Aluminum Body

Current product imagery specifically identifies CNC aluminum construction.

📏 32-Blade Thickness Gauge

Included folding gauge supports post-adjustment measurement.

🔄 Screw-Driven Adjustment

Knurled knob moves the adjustment block progressively.

🎯 Controlled Workflow

Helps replace rough bending with smaller deliberate adjustments.

4️⃣ Four Thread Sizes Shown

Current compatibility graphic lists 10mm, 12mm, 14mm and 16mm.

📐 Multiple Reach Profiles

Current graphic lists 7/16", 1/2", 3/4" and 1" reach examples.

🧰 Compact Tool-Drawer Size

Main body is shown at approximately 4.8 inches long.

🔴⚫ Red Or Black

Current live selector offers two body-color variants.

📏 THE TOOL DOES NOT CHOOSE THE CORRECT GAP FOR YOU Always obtain the required spark-plug gap from the applicable vehicle, engine or spark-plug manufacturer before making an adjustment.
🔍 MEASURE AFTER ADJUSTMENT The included thickness gauge should be used to verify the result. A knob turn alone is not a measurement.
⚠️ CHECK WHETHER YOUR SPARK PLUG SHOULD BE RE-GAPPED Some spark-plug electrode designs require special handling. Follow the plug manufacturer's instructions and never force the center electrode or insulator.
🔩 COMPATIBILITY NOTE Current seller imagery lists 10/12/14/16mm thread sizes and several reach profiles, but exact fit can also depend on the spark plug's physical design. Check the actual plug before use.
TOOL FAQ

Before You Set The Gap.

Does the thickness gauge come with the tool?

Yes. Current product imagery explicitly shows a 32-blade folding thickness gauge included with the gap setter.

What is the gap setter made from?

Current product graphics identify the main body as CNC aluminum.

Which spark-plug thread sizes are shown as compatible?

The current compatibility image shows 10mm, 12mm, 14mm and 16mm thread sizes.

Which spark-plug reach sizes are shown?

Current seller imagery shows 7/16", 1/2", 3/4" and 1" spark-plug reach profiles.

Does that mean it fits every 10mm, 12mm, 14mm or 16mm plug?

No universal fit should be assumed. Spark-plug body shape, electrode geometry and other dimensions can affect compatibility, so check the actual plug before use.

How do I use it?

Confirm the required gap, position the compatible spark plug in the setter, turn the adjustment knob gradually, then check the resulting clearance using the included thickness gauge.

Does the tool automatically set the correct gap?

No. It provides controlled mechanical adjustment. You still need to know the required specification and verify the result with a gauge.

How many blades does the gauge have?

The current product image identifies the included folding thickness gauge as a 32-blade gauge.

Are the gauge blades marked in inches or millimeters?

The current thickness chart displays both inch and millimeter values.

How large is the setter?

Current dimensional imagery shows the main body at approximately 4.8 inches long, 1.3 inches wide and 1 inch high, with the upper knob assembly reaching approximately 1.5 inches in height.

Can I use it on iridium or other fine-wire spark plugs?

Do not assume every electrode design can be adjusted in the same way. Follow the spark-plug manufacturer's instructions and avoid applying pressure to delicate center electrodes or insulators.

Does correctly gapping a spark plug guarantee more horsepower?

No. The tool is for controlled spark-plug preparation. Actual engine performance depends on the correct plug specification, ignition system, engine condition, tuning and many other factors.

What colors are available?

The current live product selector shows Red and Black.
