Which spark plug socket do I need?

Make sure the spark plug sockets are the right size for your spark plugs. Common sizes are 16 mm and 21 mm, but it's important to check this for your car.

If you frequently replace spark plugs yourself, it is wise to buy spark plug sockets that are made of high-quality material, such as chrome-vanadium steel. This material lasts a long time, so you don't have to adjust it.

Pay attention to the type of insert the spark plug socket uses. You don't want to drop your new spark plugs, of course. Rubber inserts provide a good grip, while magnetic inserts provide extra assurance that the spark plug stays in place during use. In addition to spark plug sockets, you can also opt for spark plug pliers. These have long legs so you can reach the spark plugs well. With the pliers, you have the grip in your hands.

Finally, you can choose a set or a single spark plug socket. If you work on multiple cars with different sizes of spark plugs, a set may be more economical.

Spark plug sockets

Spark plug sockets are specially designed to easily loosen spark plugs from your engine block and quickly install new ones. Spark plugs are part of your car's ignition system. You screw them into the cylinder head, where a ring ensures an airtight seal. When replacing spark plugs, it's important to work carefully to avoid damaging the connection. Properly fitting spark plug sockets are essential for this.
