Default Denso Iridium Power vs NGK Iridium IX

which one is the best to get for my is300... for best balance of performance, mpg, and longevity?

my main concern is the life of the plug/gas efficiency, that is why im trying to find out what the main difference from the denso's .4mm gap to ngk's .6mm gap...

- thanks!

Honestly, Iridium is Iridium.. you cant really go wrong with either of those plugs. I highly doubt you will notice any difference between them.

I've used both in the past. I couldn't tell a difference between the NGK & the Denso, and the NGK's are usually much much cheaper so that's whats in my cars now.

I have also tried both, that's going back awhile and also couldn't sense much of a significant difference. I ended up going with Torquemasters, which really seemed to do the deal on that Mexican gas I was running for so many years.
