thread stripped out for spark plug

You can try this but it is not likely to hold for a long period of time. So you will need to keep an eye on performance issues as it may start leaking compression.

Here is a guide that will help with drilling and tapping new threads.

Again this is not the best repair an in fact there are better options out there. I have had great success with something called a Time Sert.

I have not used them for spark plugs but they make kits just for this.

Basically this is where you drill out the treads and then install a plug that will have new threads and it is stronger then a coil.

I attached a picture below to give you an idea what they are.

If it were me, I would go this route rather then a coil.

Let us know if you have other questions. Thanks
