I think it works Ok
Amazon reminded me to write a review on these sparkies, I forgot what I bought it for since it was eons ago so here is my attempt at an honest review; sparks Ok for what it was built for, Denso QC folks should be tapped on the back for coming out with this ingenious product (I think the same people invented sliced bread). Car starts, runs and drives so well now that neighbors cat didn't get out of the way in time. Her name was Sparkles so there's no better way to sign off this existence.

Correct spark plugs, quick delivery, pre-gapped and fully protected
Amazon delivered overnight, The plug ends are well protected with a hard plastic tube to protect gap from being bumped and changed They installed as expected and all work. I would recommend. I used these in a 2004 Hyundai Santa Fe, 2.7, 6 cylinder engine.

Great Plugs
gen3 4Runner was not running well and needed timing belt anyways. Pulled old copper plugs out (40K overdue), replaced with these plat plugs and it purrs like a kitty. Customer quite happy (replaced the coil extenders and plug wire too)

No issues threading them in, just had to set the gap beforehand.
The set was OEM or better quality for a good price. They were not pre-gapped but with a little patience I set the appropriate gap for all six. Installation on the back side of the horizontally opposed V6 in the 2004 Acura MDX was a little bit of a pain but certainly not the worst job I've had to do. Engine turned right over and I don't have any apparent knock or misses. Don't forget to use a little dielectric lube on those coils though! And if you see oil pooled around the spark plug, the spark tube seals are bad. You replace those along with the valve cover gaskets. And you may as well do the intake plenum gasket set as well. That's next on my radar since I did have oil in two of my spark tubes.
