Giving your engine fresh spark plugs should be part of your car’s regularly scheduled maintenance. But you don’t necessarily have to go to the dealership or pay a mechanic to swap in a new set of plugs. Instead, get yourself an affordable spark plug socket and do it yourself in your garage or driveway.

Like shopping for other tools, choosing the right spark plug socket might come down to personal preference on brand, or just simply cost. Before choosing a specific product however, you will have to determine the correct size spark plug socket you need for your specific engine. From there, most spark plug sockets will look similar, although there is one major feature to choose between: rubber grommets or magnets. More affordable spark plug sockets use rubber grommets on the inside to hold the spark plug in place, while more expensive sockets are magnetic. This too, can come down to personal preference, although generally magnetic spark plug sockets are more reliable and last a lot longer than rubber counterparts.

Below you’ll find a list of the top 10 best spark plug sockets you can get on Amazon. Some of these are extremely affordable, while others are more expensive and come with a variety of socket sizes. Again, make sure you’re getting the correct socket for your vehicle!
