I dont see why not. NGKs are OEM suppliers just like Denso. Some toyota came with NGK plugs.
Keep in mind that NGK has 2 variants of iridiums...the Laser and the IX. The IX is suppose to be the longer lasting of the two and the laser is suppose to be the more performance oriented version. I would get the IX as the performance difference is negligible.

Most people who run F/I setup go with copper plugs simply because they tend to replace them more often, plus it's cheaper. The TM plugs for our cars are only one of a kind as in I don't think there are more than one heat range available, making it less ideal for boosted application.
I ran OEM denso, TM, and NGK iridiums. All 3 plugs did their job, and TM gave me a small gain on the top end. When I slapped on a set of brand new Denso plugs, boy did my car feel slower. It felt better with the NGKs.

my fuel economy probably went up by 1mpg highway, only because my OEM denso at the time had 30k miles on them already.
I sold the TM plugs because my friend kept on bugging me to go back to OEM. I bought a new set of Denso and boy did I regret it. In the end, I lost half the money on the TM, and I had to fork out an additional $65 for new Denso. I could feel a bit less power throughout the rev.

With TMs in my RX, I noticed nothing when I used them on basically a stock vehicle many years back, but when I started doing exhaust/intake modifications, they just came to life where NGKs and Densos didn't. Plus, with the atrocious gas down here (only a few more days of that until Florida), you need something that can really burn through this stuff. The Pulstar plugs I have thought about giving those a try. I do have some worries about the coil packs given the way the Pulstar works, but it seems to have been tried out in a number of vehicles with coil packs, and I haven't heard of an issue yet.
