First round of work yesterday - plugs/wires/coils/airfilters + cps, valve cover gaskets, an oil change and windshield wiper washers. Was definitely time for new plugs.

Pros: new plugs

NGK Spark plug

Have them for 15,000 miles on these and frankly can't tell the difference from (spec. plug) with original that it replaced. Gas mileage is no better and no worse.

The plugs said "DO NOT GAP FACTORY SET" Every single plug in every box was the wrong and different gap and had to be redone. Some with the electrodes damn near touching.

Cons: wrong gap, electrodes touching
