This instructable is to show you how to make your own inexpensive tool to extract that broken boot off of the spark plug so you can continue with your tuneup.

For you DIYers that work on your own vehicle, there's nothing like replacing your spark plugs only to find out that the boot on the end of the wire has stuck to the spark plug and has detached itself from the wire/coil pack way down inside the spark plug tube.  There is a commercial tool that costs around $30 but who carries that tool locally? 

Step 1:

Using a 6' garden stake with a steel inner core purchased for about $3 at your local hardware store (Ace Hardware, Lowes, Home Depot), cut off about 12" from the blunt end with a hacksaw.  The one I purchased was GardenPlus 6' garden stake, item# 0093249, model# 831138 from Lowes.  You can make about 6 tools for the $3 investment.

Remove the inner core end plug from the blunt end of the cut stake and discard the plug.
<p>THANK YOU for this magic tool! Depicted in the photo below, removing the stuck boot took mere seconds: push tool onto plug with stuck boot; rock tool around in circles; remove; the boot comes out with the tool!</p><p> Subaru Foresters have boxer engines where the engine's valve covers and the body's frame are just two inches apart, barely leaving room to get a wrench onto the plug, which is deeply nested between two overhead cams. The second photo shows how the socket, extension and wrench must be disconnected in order to be put in place. Not just any plug boot tool could also fit into this awkward space. This tool did the job instantly, with cheap and available materials. Thank you, thank you, thank you!</p><p>Th</p>
<p>Nice. After reading about this problem on different vehicles and makes, making one of these tools is a must. So I did. <br><br>NOTE: When placing a new C.O.P. boot onto the plug, use dielectric grease to prevent this from happening on the next plug change go around. </p>
<p>there have been times in the past I could have used this. I drive a diesel now but will keep it filed away. </p>
<p>This was an instructable that really helped as I was totally lost as to how to get the car back on the road. Thank you so much.</p><p>I am so glad there are people willing to share knowledge like this.</p>
<p>I'm glad my Instructable was beneficial to you. Just out of curiousity, how did you find out about this?<br>I made this tool after fighting with my neighbor's broken spark plug boot in his truck and didn't find any easily accessible tool to the common person. I keep this exact tool in my truck at all times just in case I'm trying to help someone else change out their plugs and find another broken spark plug boot.</p>
