Jebus, I had to change plugs about every 500 miles in my talon. How the hell do you get that many miles out of them?
A good tune. :) My plugs have never not looked like that and my car has proven issues.

Time to buy an Evo I guess. ;)

Does the COP make each cylinder fire individually or is it still wasted spark?

I could be wrong, but I believe it is still wasted spark and fires the same as the stock ignition. I'm sure Scheides will correct me if I'm wrong on that though.

They are iridium spark plugs and Mitsu has a recommended replacement interval of 60k miles.

You're right! The thing is the DSM uses an ignitor that then leads to the coils, so I'm not sure quite how it would all wire together, since the evo doesn't (I don't think?) have one of these. I think you'd just need the right plug and then the wiring would of course be a bit longer. I'm sure its very possible :)

I just measured my stock plugs and they came out at (passenger to driver side) .025", .025", .023", .027" gap (factory spec is .020-.024" gap).

The iridium plugs are made to last longer than our DSM copper ones. Might have something to do with why they look cleaner. The iridium ones on my Envoy are rated for 100k mile intervals.

I tried running iridium plugs in my DSM just after I got it (they came with the car), and on a stock tune with just a small 16g (14psi), the electrode was almost completely burned away in under 3k miles. Went back to regular plugs and never had another problem.
