Michael: My ACT sensor has a plastic housing, how can it be grounded? Do I have the wrong sensor? The threads matched the stock intake and the harness plug fits perfectly. I have the ACT mounted in the intake tube.Michael Yount said:

Made it easy to douse it in ice water before a run. You know the EEC-IV pulls timing when it reads warm/hot right
