At 12-15 psi I always had the best performance with the OEM wires when using
OEM coils. They're designed for each other. As for lifespan, it's more a
matter of time and temperature than of miles. Change them if either the wire
or boot insulation starts to get stiff or starts to crack when bent, or if
either develops a pinhole that a spark leaks through.

stick to OEM NGK stuff and change it once a year for piece of mind...

Up until August of last year, the car was frequently street driven. I

the last time I changed the plugs & wires was a year before that. The car
is now used only for DE's & driven (hard) once a month. Thus far, it's
been
to the track twice this year for 2-day track weekends. Typically, I run
through a tank of gas (100 octane) a day. Car is making a good 220rwhp at
12psi of boost. I don't ever see any knock & the fuel mixture is a little
on the rich side but not terribly so (A/F = 12-14 depending on where in
the
MAP).
I haven't noticed any misfires or stumbling but don't want to wait until
that happens to change the spark plugs &/or ignition wires. What's the
conventional wisdom on when to change them for my application (only DE's)?

Sonny
With boost, I've had no difficulty running NGK extended reach plugs, those FM
sells (ZFR7F11 or something like that...)
