A:  You chose the size you want to use put the small handle thru the two small holes and twist....and out comes the spark plug...

by|Jun 3, 2020

A:  It’s pretty intuitive. There are multiple sizes. Choose the size of your spark plug and use the metal shaft to leverage the wrench to loosen or tighten the plug.

by|May 18, 2021

A:  1. Take the spark plug cover/wire off 2. Identify which spark plug socket you need. This wrench has 2 sizes. If the socket fits over the plug snugly, then that's the one to use. There are spring loaded buttons to allow the wrench to extend. 3. Use the long metal pin inserted through the holes at the end of the wrench to turn the plug (lefty-loosey, righty-tighty). 4. Once the spark plug is free, pull it out, and replace with the new plug (ensure the right gap is used). Tighten using the wrench, but do not over-tighten. You won't need a breaker bar for this or anything. Your engine manual may have some guidance on how tight to get your plugs.

Q:does it work for 18mm plugs?
by|May 5, 2017

Answer This Question

A:  Yes

by|May 4, 2023

    A:  It fits all spark plug that I am aware of, since it has four different sizes: 16mm/.63", 18mm/.71", 19mm.76", 21mm/.83" Just be aware that the two pieces are longer than a socket wrench, at 104.5mm/4.1", and there may be some applications where you may not be able to get it onto the spark plug. Push the spring loaded ball VERY hard to separate the two pieces!

              A:  Push in the little buttons. Use the handle to do so.

                A:  Use a flathead screw driver and reach in with it to pull down the lever (which will "depress" the button). After 20 minutes killing my fingers, I opened it with the screw driver in less than 30 seconds.

                  A:  Use the rod to push the locking tab into the wrench piece. Then pull the inner piece out by the larger end. If it sticks, push the inner piece with the rod from the small end towards the large end. After separation of the two pieces, make sure the locking tab is completely back in position or the locking tab will block the spark plug from entering the wrench.

                    A:  Use the bar to push the button in and pull from both ends. There may be a tight fight from the factory that will loosen with wear - or some light sandpaper and a little oil.

                    A:  Simply push in opn BOTH of the spring-loaded "balls", which are connected by a "V" shaped spring, then pull the two sections apart. You need to push pretty hard, the V-spring is very strong!

                      It looks like it should of come with a handle, but once we figured out how it worked, it did the job as advertised.
