Other Components (generally accepted values)
Spark Plug Wire Resistance
All wires should be within
10% of each other when you measure
ohms per foot.
Spark Plug & Gap (High boost)
(if stock boost levels)
(on the Turbo TA)AC-CR42TS .035" or
AC-CR43TS .035"
AC-R42LTS@.035" for TTA
Coil Tower Resistance
