I really don't think you can go wrong using either one. Both brands are designed with the utmost quality and are built to the exact specifications for our cars. In the past I've bought NGK because they were more readily available as well as a little cheaper, but I'd sway to the Denso side if I found them cheaper instead. Good luck.

Cant go wrong with either one. I just put Densos in last week and all is good
I installed Denso iridium plugs in my ES two years ago when the mileage was close to 90K, and since then I haven't had any problems. The factory ones in my car were the NGK.
I have had TMs twice in my RX300. The first time, just a K&N filter and no difference. However, with all my other modifications, big difference and it feels like every last little drop of gas is getting burned cleanly. I would estimate it dropped me at least .1 in the 1/4 mile the first time I tried it. Keep in mind my Denso plugs were less than 1 year old when I put in TMs the second time.
Denso's have a slightly finer wire than the NGK's , 0.6 to 0.8 I believe , so the Denso's might burn slightly better but won't last as long , I think the factory reccomended mileage is less for the Denso's than the NGK's .
Personally I don't use anything but NGK's !!
When I owned my 2003 4Runner, I changed the plugs after 30K and found a mixture of the two types in the motor. I called toyota and they said it was pretty normal....wtf??

I changed mine in my 04 Tacoma as well and 3 densos on one side and 3 NGK's on the other. Wierd huh???
I've used 'em both. It's really hard to pick one over the other. Both are the best plugs I've used.
However, I just put in Torquemasters (TMs). GS is now like a rocket ship. Unfreakinbelievable.
iridium plugs - NGK or DENSO?
