OBD II port

That is what I figured. Also, do not use anti-seize on the threads of the new plugs?

Oh okay, did not know that. So they will not seize in the screw holes right?

Thanks Roy. Hey I believe the torque specs are 15-21 ft lbs for my car according to what Ken said in an earlier email. Can we double check because you mentioned 28 ft lbs. In your recent email. Thank you Roy.

That is interesting. Thanks anyway Roy.

Hey Roy, I changed my plugs and they looked pretty eroded. Two were about.050 which is factory range and two were way wide about.060 or more so that was my gas mileage and performance dropping answered. Also, I just did a 3 to 9 clock or 1/2 turn once they were threaded by hand instead of using the torque wrench, should be good huh? Seems to run a lot better. Should I change the wires as well?
