Speaking of spark plugs - my 60k is coming up - so how many of you are running 1 range colder plugs?

Also - I did get a misfire on the dyno so i'm gonna be ordering some sooner than later. I'm looking at the usual NGK and Denso plugs - and also possibly the NGK iridiums (unless of course I hear they are complete crap). Not gonna go with the copper-change-every-5k plugs.
So who's using what? On the one hand i'm thinking 1 range colder - on the other - i'm thinking i'm not that heavily modded.

NGK PFR6Q...
(Audi spec) they're the only ones I've had which will go 50K without misfiring. I take that as an indication that they're working better during that time, too (more margin). Audi didn't spec a Japanese plug without a good reason. A plug won't increase performance, but the wrong one will certainly decrease it.
