Performing maintenance on your car in your garage is a great thing to consider doing. Not only is it easy on your wallet, it's also mentally stimulating because you constantly have to learn all kinds of new things in order to successfully perform the maintenance. One of the most important repairs you can perform on your vehicle is changing your spark plugs. In order to make this easy on yourself, you'll need a spark plug socket.
They generally come in two sizes: 5/8 and 13/16 inches and they work by fitting down around the spark plug to make it easier to remove. The better spark plug sockets on the market also have some way to hold the spark plug in place, inside the socket, once you remove it from your vehicle.
What spark plug socket is best though? All of the best spark plug sockets on this list have some sort of feature that holds the spark plug in place after removal (like I mentioned above). Also, spark plug sockets generally aren't very expensive to begin with, but all of the sockets on this list come with a lifetime warranty.
The 5/8 in. Spark Plug Socket, 6 pt. Flex by Craftsman is the top spark plug socket because of its corrosion resistant finish and flexing head that makes it easy to reach any spark plug. Read Full Review
The 5/8 in. Spark Plug Socket, 6 pt. Flex by Craftsman is the best spark plug socket available because of its nickel chrome plated design. This plating makes the socket resistant to rust and corrosion. This is great if you don't plan on using it very often and it will be stored in your garage, where weather exposure is more common. I also love the flexing feature of this socket. It makes the tool more valuable because it increases the easiness with which you will be able to reach the sockets in your vehicle. That's a good feature to have if your car has spark plugs in a hard to reach or tight place.
The 3/8 in. Drive x 5/8 in. Extra Long Spark Plug Socketby Tekton is one of the top spark plug sockets because it has a corrosion and reflection resistant surface and it has a locking drive end. Read Full Review
The 3/8 in. Drive x 5/8 in. Extra Long Spark Plug Socket by Tekton is great because of its black oxide finish. Black oxide finish is great to have in a tool because it not only reduces corrosion greatly, it also cuts back on the amount of light that the tool reflects. If you have ever worked with a chrome plated tool in the hot sun for hours, you know how hot they can get. If you live in a place that sees lots of sun, then this is a great tool to consider. This socket also has a notched drive end. This will lock the socket onto whatever ratchet or extension bar you use it with, which is a great thing to have if you're at all worried about dropping your socket.
The 80546 5/8-Inch x 6-Inch Swivel Spark Plug Socket by GearWrench is one of the best spark plug sockets available because it has an angled entry point and it swivels. This makes hard to reach spark plugs very easy to take out. Read Full Review
I have included the 80546 5/8-Inch x 6-Inch Swivel Spark Plug Socket by GearWrench on this list because the entry point of the socket (where you place the socket onto your spark plug) is angled down. This helps make changing your spark plugs easier by guiding entry. An angled entry point is good to have if your spark plugs are in a tight place that doesn't offer a whole lot of visibility. This tool is also a swivel spark plug socket. What that means is that the socket swivels in different directions to allow the socket to reach strangely angled or hard to reach spark plugs. When you combine these two features, you get a socket that is great to have because it makes even the remotest spark plugs simple to take out.
The Duralast/3/8 in. drive 5/8 in. spark plug socket is a decent socket to consider picking up because it has a magnetic spark plug retainer to raise grip. It also has a large extension bar to increase ease of use. Read Full Review
The Duralast /3/8 in. drive 5/8 in. spark plug socket is a solid choice because the plug retainer relies on a magnet. This allows it to grip the plug you take out a lot better. Most spark plug sockets that have a retainer use rubber, so the magnet makes this socket a lot better in terms of grip. This is also great if you ever end up having to use your socket in the rain, where the water might affect rubber's gripping capabilities. That won't happen with the magnet. This socket also comes with an elongated extension bar, giving the socket an overall length of around 15 inches. If you have spark plugs in awkward places, then this socket is perfect for you because the extension bar eliminates the need to stick your hands down into the engine.
The Extended Spark Plug Socket 3/8in. Drive, 5/8in., Model# W80533 by Performance Tool is one of the best sockets because it's inexpensive, it's extra deep to make removing hard to reach spark plugs easier and it has a knurled grip. Read Full Review
The Extended Spark Plug Socket 3/8in. Drive, 5/8in., Model# W80533 by Performance Tool (Wilmar Corp) is great because of the quality you get for the price. At around $5, this socket is incredibly easy on the wallet. Plus this socket is also deeper than other comparable tools at 5 inches long. This extra length is good if your spark plugs are in a hard to reach place and you don't have an extension bar to use. The final reason I have decided to include this tool on the list is because it has a knurled design. This increases the grip of the socket, which is good to have if you ever get sweaty palms while working.
