It may be a semantical point but these are not Helicoils. Helicoils are expressly not indicated for spark plug bore repairs. A Helicoil (known generically as wire thread insert) is a square wire wound up in a tight coil, hence the name. Helicoils are intended for repair of fastener threads such as you where would insert a bolt to keep two parts together. You can pull a Helicoil apart like a spring. http://www.emhart.com/products/helicoil.asp
These are actually inserts or solid metal bushings that are threaded on the inner and outer diameter of the insert. This is a link, which is apparently sold under the Helicoil brand name. Mine weren't branded that way, but the package looked almost the same. http://www.globalspec.com/FeaturedPr..._x_125/23773/0

So how the heck do you get that tool down in the tube and do the "reaming" required, and get the insert put in properly? Seems like a lot of faith required to just shove it down there and hope that it doesn't go in crooked, etc.
