JimD Posted March 20, 2005 Report Share Posted March 20, 2005 Replaced the plugs (and wires) in my '98 recently. Since I expect to drive this one for another 50,000 to 100,000 miles, I would be replacing these parts at some future point any way you slice it. Engine was lighting off as quickly as it did when new, hot or cold. No misses, no stumbles, slight degradation in fuel mileage. All of the ground electrode platinum pads are gone. Gaps ranged from 0.056" to 0.068". Color is good (slightly off-white). This engine sees regular WOT exercise. Pictures available. Speaks well of the OEM ACDelco plugs. Jim Drive your car.
