SPARK PLUGS/WIRES

[JACK LEJA]

I just got Underdog HeatBraid 8mm silicone plug wire set, Screamin' Demon Coil Pack and going with double platinum Motorcraft or Autolite plugs.

The instructions for the wires say that the plugs should be gapped to .060-.065....

Does it make a difference if I stay with .054 or should I go with .060-0.65?

You won't see full benefit without re-gapping the plugs. That being said, I didn't re-gap and I'm happy with how my truck runs.

I gapped mine and it runs great. . .
