Default When is it time to change plugs and wires?

I've got 88,500 miles on the original factory plugs and wires from the day the car rolled off the assembly line. Motor runs fine with no codes. The only code it'* ever had was a P0452 - Fuel Tank Pressure Sensor - which I replaced. Should I wait until they're completely shot and get a misfire? GM recommends replacing them at 100K. Shall I just wait until there'* a problem before I go out and splurge? What would you do?

I would go with the interval of 100k if thats what they recommend. But I thought it was something like 60k. Maybe just for older cars like mine.

MAC, I would do the change now. Age of the plugs & wires alone would warrant replacement. My .02 May improve engine performance a little also.

GM recommends oil changes between 5,000 and 7,500 miles.. we don't follow that recommendation and our cars last longer.

Mac.. it'* time, I waited on my truck.. Gap was triple what it should have been.

Thanks for the highly valued replies fellas.

I'll alert the budget committee of my intended purchases. That means I'd be talking to myself.
