Yeah, you can get anything you want with this wrench: pre-calibration, the storage case, the manual, the adjustable ratcheting handle. It has a reduced size and torque range.

The Buyer’s Guide

If you seek the correct installation of spark plugs, a special torque wrench must be applied. Any professional torque wrench for spark plugs allows installing the parts in compliance with the required torque, which is specified in the manufacturer’s guidelines.

What can happen if you do not use a special tool to screw spark plugs?

Most breakdowns associated with spark plugs occur due to improper installation and failure to comply with the tightening torque. A plug that is not tightened to the required value can cause the following breakdowns of your vehicle:

  • Possible loss of compression;
  • Overheated plugs;
  • Vibrations can break the centerpiece electrode or insulator;

On the contrary, a properly tightened spark plug can lead to the following consequences:

  • You can provoke a breakdown of the upper insulator and then damage it. Because of this, it begins to scroll around its axis;
  • Using a lot of effort, you can break the plug;
  • Strong tightening can lead to expansion of the body, disrupting normal heat dissipation;

As you can see, hauling the spark plugs may lead to unpleasant consequences. Please when installing spark plugs, use a proper torque wrench.

What best torque wrenches for spark plugs I recommend:

  • TACKLIFE is the best pick with the most accurate range – 13.6-108.5 Nm (4%);
  • TEKTON 24330 is also great due to the 24-tooth gear ratchet;
  • EPAuto is a quite lengthy instrument with the same parameters;

Pay attention to the fact that the package of any spark plug must indicate the torque used during the installation of a vehicle’s engine. Based on this value, it is necessary to choose a specific torque wrench for plugs.


Beam wrenches. One of the simplest and most affordable options for people who want to repair their cars on a budget. Such a wrench has a simple design and low cost. In terms of accuracy, they are inferior to competitors, have an accuracy percentage of up to 10%. In this case, do not count on a maximum tightening torque range of more than 280 Nm. Among professional car repair mechanics, such wrenches are not in demand. However, if you carry out work in the garage, and the procedure does not require increased accuracy, this tool should be quite enough.

Click wrenches. They are the ultimate instruments for spark plugs. For such tools, the torque range can vary from 40 to 360 Nm, which already significantly exceeds the capabilities of a standard beam wrench. This range greatly simplifies the selection of a specific tool with the necessary characteristics. Such instruments are quite versatile. The accuracy percentage does not exceed 5%.

Digital wrenches. Having it mind the torque range recommended for your car model, you may choose an electronic wrench. This is the best tool for car maintenance, although it is rare in the garages of DIYers and car repair experts. This is a professional-grade device with the highest technical specifications. The measurement scale is electronic, and when the desired range is reached, an audible signal is sounded, often supplemented by LED indicators. The range starts at 20 Nm. However, the most significant feature of such a wrench is an error that does not go beyond 1%. The only but significant reason to refuse to purchase an electronic device is the price.


The use of these adapters improves functionality and does not affect the accuracy of the tool. If you have a choice of a torque wrench, then it is better to purchase a kit with interchangeable nozzles and different drive adapters.

Why should you use these tools?

The spark plugs typically break due to improper installation or over-tightening. The plug that is not tightened to the set range can cause the following issues:

  • Possible loss of accuracy;
  • Overheated spark plugs;
  • Vibrations may break the center insulator;

On the contrary, an over-tightened spark plug may cause many troubles:

  • The insulator may break if the plug is too tight;
  • You can break the plug if it is over-tightened;
  • Over-tightening can lead to expansion of the spark plug;

Final thoughts

In the guide, you can find the right torque wrenches for nuts and spark plugs. It is not a complete list of all the good tools on the market, however. You may continue this list on a steady foot. Check the comparison table to pick the wrench that suits your daily tasks.

I’m a Matthew Johnson, and I’m a motor mechanic. I like my profession and every day I use many tools, but a torque wrench is most useful of them. I’m going to write about my experience of using different torque wrenches and share with you.
