Spark Plug Ohm Meter Testing?
Like the title states, can it be done?

What values would you expect to see?

Thanks

Msd -8mm red wire = 40 ohms per foot . Accel 8mm super stock wire = 500 ohms per foot , Junk wire ,cheap wire can run 3000-7000 ohms per foot .

You can test the wires usinig an Ohm Meter, however, I don't think you can test the plugs with one. There are testers that will do it for around $10-15 if you want one.

Cool thanks, thats what I was getting at. I have just noticed that the four new plugs I bought have a weaker spark then the cleaned up old ones. Weird.

Thanks
