I run these in one step colder on my turbo setup. FI increases chamber temps so cold plugs reduce the chances of detonation. I get misfires when cold some times. I would NOT put them on my NA car.
I have them on my car. I would not recommend them as the driving is a bit rougher. I had a set of the NGK sparkplugs for the leading plugs that were one heat range colder and they were better. Smoother idle.

I have them on my car for months.
Not sure how effective they are because I changed them with Autoexe spark plug wires concurently. I noticed the rev response was faster in first few dasy after change.
According to the info come from denso website, these plugs have silicon coating for preventing flood.
Hi
I had a big embarresment today, my RX8 has about 29000 miles (46000km) on the clock. while in heavy traffic it started to miss and loose a lot of power which felt to me as failed plugs. here in SA the services only say (at the dealers) to replace plugs at 60000km or 38000miles. Did anyone come to this mileage yet or did anyone get this behaviour before.
I hope it is plugs.(as soon as throttle is a bit more opened and a bit under load, then it feals like a brake and as if you switch off)

more than likely it is going to be the cat. as to the plugs, mine were toast at 30k miles.
