replaces maybe but does it WORK and LAST more than a few hours? or do they miraculously come with a lifetime warranty? (guaranteed for the life of the plug!!)

i find it interesting how it can replace 3 different heat ranges of otherwise same plug. Especially when for gcv160 honda changes the heat range by 1 unit if engine is on a pressure washer. I've come into possession of a gcv160 with that plug in it.

I would get rid of that "Miracle"plug and replace it with the proper NGK plug.

Second that. Besides it could screw up those EPA emission compliant engines. Some the ignition coils nowadays don't work right either with alternate plug.
