Did you "gap" them. Don't trust the place you bought them from, they don't know always Gap them unless you ask, and even then they may pick the wrong gauge.

99.9% of the new plugs are gapped "spot on" right out of the box. The plug companies have a reputation to uphold for quality control. More likely you didn't put the plug wire on tight. Or, switched two of them by accident. Recheck.
