Spark Plug wire resistance

Recommended Posts

pfrederi

My question is about the appropriate level of resistance in spark plug wires on a KT-17 in a c175. Most of my old stuff has copper core spark plug wires so the appropriate resistance level is near 0.

The KT-17 (and i fear the Magnum 18 on the 418A) use new fangled carbon core wires. I have looked through the KT-17 service manual and cannot find any spec for resistance reading on the plug wires....

Is there a generic acceptable resistance level per inch of wire???

What I got was 6800 Ohms on #2 wire (9" long) or 756 ohms per inch and 10,500 Ohms on teh #1 wire (18" long) or 583 ohms per inch.

Would I screw anything up if i just replaced them with good old copper wires??? .... I really do not give a damn if I interfere with somebody's cell phone or wi-fi :thumbs:

I don't see anything it could hurt, it's just a wire from your coil to the spark plug.

Plain copper wire is best, the high resistance

stuff is for R.F. noise. :thumbs:
