Why Do You Need a Torque Wrench for Spark Plugs?

A spark plug is an important part of your car’s engine. It mainly helps in the combustion process that powers your engine to drive the car. That’s why it is essential to install the spark plug properly.

Many car owners ask, do I need a torque wrench for spark plugs? If you are thinking the same, you have come to the perfect place.

Yes, you need a torque wrench for spark plugs. Spark plugs in cars require a specific torque. It is impossible to achieve accurate torque without a torque wrench.

But what happens if you do torque spark plugs accurately?

The answer is:

Loose Spark Plug: Spark plugs seal the combustion chamber. A loose spark plug means a leak in the vehicle’s combustion chamber. It will cause the chamber to inhale oxygen.

The excess supply of oxygen inside the combustion chamber can cause the engine to misfire or lose power. It is essential not to leave the plug loose to avoid accidents.

Over-Tightening Spark Plugs: Now, what if you over tighten the spark plugs? The most common outcome is damaging the spark plug. If you put too much pressure, you may accidentally break the spark plug.

Besides, it can cause internal leaking too, which can lead to engine misfire.

It is apparent that you should follow the manufacturer’s instructions to select the torque for your spark plugs. People will say you can do it without any torque wrench. But there is no reliable way to do that.

You need to purchase the best torque wrench spark plugs for your vehicle. But what are the best torque wrenches?

Let’s find out the answer!
