The 6 Best Spark Plug Wrenches

Updated September 06, 2019 by Rafael Perez

This wiki has been updated 15 times since it was first published in July of 2019. Most internal combustion engines use spark plugs as an ignition source, and these specialist wrenches allow mechanics to remove and replace them easily if a cylinder is misfiring or they are not producing enough current. There are many different models available, and our selections considered factors such as affordability, build quality, and the design of the grips. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.

Editor's Notes

September 03, 2019:

Spark plug wrenches are special tools that often come with retaining mechanisms because, when working on cars (specially with the rise of the over-head cam engine configuration), the spark plugs will be deep in a well that cannot be reached by hand. Spark plug sockets use either rubber grommets or magnetic retainers to pull the plug up after loosening and also to ease the plug back into the hole when installing.

In my experience, grommetted spark plug tools such as the Craftsman 8-Piece and the Senzeal 43237-2 tend to lose the grommet on the plug electrode after you tighten and want to pull out. Most tools simply do not do a good job of fastening the grommet to the inside of the socket. The magnetic sockets like those that come in the Gearwrench 80601 and the Ares 70045 do not tend to have this issue and that is the primary reason they are ranked higher than the rubber grommet models.

Working on engines and automobiles is dangerous and should only be performed by trained automotive and engine technicians to avoid personal injury or damage to property.
