Quick spark plug question Just got done changing my O2's and I was throwing in some new plugs as well since it's almost been a year. Anyways, I forgot my haynes manual and I had a couple questions. First off, what's the correct gap? .55? This is on a stock car. Also, what's the torque specs? 17 ft-lbs? Isn't it like 3/4 turn past fingertight? Quick help would be appreciated. Thanks guys

Thanks guys. I just checked all of mine and they are 53-54. What difference would it make by dropping it to say 45?

plug gap would be in order, since the mixture is more dense. The smaller gap
ensures a clean spark.

for in the gap. For example, I didn't know this - I use NGK TR55's and they recommend
a gap of 0.044, for all versions of the TR55. I know for a fact I gapped them at 0.050,
which means I'm off For NGK, start here:
