A great product.
I have been working on cars my entire life, I am an ASE Certified Master Mechanic and this product is great. This allows you to repair spark plug threads in a head without removing the head saving customers hundreds of dollars and not to mention downtime The only thing I would change is in the instructions they have you blowing out the filings with air and instead I would recomend that you use a piece of 3/8" vinyl tubing about 16" long taped to a crevis tool and a vaccum cleaner to suck up the filings instead of air that I feel will only force the debris to lodge between the piston and cylinder wall. If you have access to a bore-a-scope you can see that the vaccum does a fine job of removing the filings.

Should have been installed at factory
This what Ford should have equipped all their aluminum heads with. One per cylinder would have prevented much strife & frustrsation. Ford owners know what I mean.
