I've been running 1-step colder double platinum for the last 30k miles or so with 0 problems...ran them in 100 degree temps and 0 degree temps. The idle is alot smoother I think and the car runs fantastic...typical stage 2 but fully tuned 17.5 psi right now.

When I went stg 2 in my old car with one step colder plugs, the car didn't run very smooth sometimes. It randomly misfired. With stock plugs it was much better.

When I custom tuned my stage 2 map and starting running more boost and more agressive timing I switched to 1 range colder. Also gapped to .028 instead of .030. Car runs strong as hell! Ran a 13.1@103 today.

There was a test done recently, the article is in Import Tuner magazine regarding the testing results of stock copper plugs, platinum plugs, and iridium plugs. To the skeptics, the iridium plugs actually showed quite an improvement over stock or platinum plugs, so I don't see how there can be any argument against them...other than the fine tips that can tend to snap off if you're not careful. You will be fine with the 1-step colder plugs, give it a shot but stick with NGK the Denso plugs are junk.

Why are Denso's junk? Ran Denso's in my commuter car (Acura Integra) for nearly 80K and they still look and perform brand new.

Sorry, just personal experience with them, that's all. I'm sure there are plenty of people that have not had any issues with Denso plugs, but I had to replace 4 sets of them in a matter of 2 months on the Nissan I had, the electrodes kept snapping off for no reason.
