the car does use a resistor spark plug - R45TS. The wires are a 7mm
construction, I bought the cheaper wires from work, as this car has
already sapped a little more money than I wanted to spend on it.
The wires were slated to be replaced anyway. I was just curious with
the resistance on more of a science experiment level. I looked into the
Haynes manual and it didn't list resistance specs on the wires.
You think 2k difference is high eh? I wasn't sure what to expect when I
tested them. However I am not surprised given the condition they were in.
I did some googling and theres a lot of debate over plug wire resistance
in relation to EM suppression... and if it even matters.
