Spark blow out was mostly on the 97-03 5.4 engines. Then Ford went to the 5.4 3v (3 valve) version and those had those really long, 2 piece plugs that would break if you tried to remove them after 100k miles..
Sounds like just a 'time-sert' fix.. Sure, a quick fix, and i've never had to do one, so no comment there.. Just what I've read on the interweb and, well... There you go..
Good luck!

I like the simplicity of the fix I used, compared to all the other fix systems I've seen. No drilling or shavings to blow out, just a simple self tapping new seat in one easy step. Little chance of failure by running the new seat in to deep like other methods since this fix has a positive bottom out to stop at the correct depth. True, this fix applies to earlier than 2004 engines I believe. My brother has a newer FORD Exploder as he calls it. He had to do the spark plug removal tool trick of which you speak, 4 times. He also has exhaust manifold to head issues. He has a host of other fixes he's done or still has to do. Is there no safe haven from poorly or under engineered vehicles.
