NGK Iridium's...Anyone using these?
#4
I switched from NGK Platinium to Denso Irdium. The reason I went with Denso is that the electrode is at .04 mm compared to .7 mm that of the NGK Iridium. The smaller the electrode the better the arc is, and less power to make spark. Go to Denso's site www.densoaftermarket.com I think they compare plugs. Didn't notice a big difference but car runs alittle bit smoother and fuel mileage increased a very slight amount.

Recently switched from Denso Iridium to NGK Iridium. The butt dyno says they seem to be just fine.
I may have noticed a slight dip in fuel economy though. Not sure... I need to take care of some other things before I can be certain.
