You can helicoil it right on the car. suck as many chips as you can out, then just fire it up. The alum chips wont hurt anything.

x2 - have done it a bunch of times. Be careful when tapping the new threads for the insert, so it's concentric with the hole. When done correctly, it will be stronger than the original threads.

Put some grease on the tap if you plan on doing it on the car. That will hold a lot of the alum. chips.

I use these in any racing aluminim heads to start, saves alot of head aches later on. http://www.timesert.com/html/sparkplug.html

You can go to Oreilys and they have a sparkplug hole repair kit. I used one on mine and it worked great. It comes with everything you need, what it does is, it cuts the hole bigger and then you screw in an insert. awesome repair job. Make sure you loctite it in though. Like a brand new piece when your done. later.

I know I posted in the trash or be trashed section on this but the lock & stitch product is worth the high price tag. Look into it
