Denso or NGK?
I have a set of Denso Iridium IK20's and NGK Laser Iridium ILFR6A's on hand, can't decide which ones to try out on my '04 C230 Sport.
What would you guys put in between these two?

I use Denso Iridium's because of their .4mm electrode which requires replacement at 30,000 intervals. Everyone else uses a .7mm electrode which lasts much longer, but i'm willing to sacrifice longevity for performance.
Some question if the .4mm diameter is too fragile since it has broken off in a few cases. If you run a car with a heavily modified engine with huge turbo's and such, i'd stay away from them. If you were running a Subaru WRX STI, Denso's would not be the best choice. For a supercharged Mercedes, it's just fine.
Otherwise, I choose Denso over NGK every time.
