Should you use anti-seize on spark plugs? This question often arises among car enthusiasts and mechanics.
The answer isn’t straightforward. It depends on the type of spark plugs and the recommendations of the manufacturer. Anti-seize is a lubricant that helps prevent parts from sticking together. Some argue it makes spark plug removal easier and prevents damage.
Others believe it can cause over-tightening and spark plug failure. Understanding when and how to use anti-seize can help you maintain your vehicle better. Let’s dive into the considerations for using anti-seize on spark plugs, focusing on popular brands like AC Delco and NGK. This guide will help you make an informed decision for your car’s maintenance.

Do Ac Delco Spark Plugs Need Anti Seize
AC Delco spark plugs are designed to fit without the need for anti-seize. These plugs come with a protective coating that helps prevent them from seizing in the engine. Applying anti-seize can alter the torque values, which might lead to over-tightening or damage.
For this reason, AC Delco recommends installing their spark plugs dry. It helps ensure the correct torque and proper function. Always follow the manufacturer’s guidelines to avoid potential issues. By doing this, you can maintain engine performance and safety.
Do Ngk Spark Plugs Need Anti Seize
NGK spark plugs are designed with a special coating on the threads. This coating helps prevent the spark plug from seizing in the engine. Using anti-seize on these spark plugs can lead to over-tightening. Over-tightening can damage the threads in the engine block.
The coating on NGK spark plugs acts as a lubricant, so there is no need for extra anti-seize. Applying anti-seize can also affect the torque reading when installing the plugs. This can result in improper installation. To ensure proper function and longevity, it is best to follow the manufacturer’s recommendation and avoid using anti-seize on NGK spark plugs.
