A spark plug is provided providing resistance to fouling. The spark plug includes a metal shell having a first end, a second end and an intermediate portion that collectively define a central cavity. The spark plug also includes an insulator that extends through the central cavity of the metal shell. The insulator includes a first end portion extending through an intermediate portion to a stepped tip portion having a first length. The stepped tip portion includes a first section and a substantially straight second section having a second length. The substantially straight second section includes a segment that extends beyond the second end of the metal shell to a third length.
