Sometimes getting at the spark plugs on modern cars (or older muscle cars as well) can be a real trick. Along with the digital torque & angle wrench we wrote about yesterday, Snap-On recently released a low-profile spark plug socket that we’re definitely going to check out.
The idea behind the low-profile spark plug socket is that it’s not intended to be used with a standard ratchet. Instead, both ends of the socket are open and the spark plug can extend right through the socket. The end that would normally attach to a ratchet is instead cut to fit a 7/8″ external hex drive. You could drive it with a 7/8″ socket, or in really tight quarters you can turn it with a 7/8″ open- or box-ended wrench.
Snap-On also touts the socket’s “patented tapered hex design” to retain the spark plug securely without a rubber insert or a magnet.
Starting at $25, this will be a great tool to own.
