spark plug wire type


Recommended Posts

Hi all, working on a Canadian 1950 Dodge D34. Spark plug wires look 40+ years old and are in need of replacement. I have made spark plug wire sets for HEI setups before. Done some searching here and it seems to avoid carbon wires and use copper core wires. I have found most of what I need at Napa, however they have no copper core spark plug wire nation wide. They do have 7mm spark plug wire with a "tinned metallic" core (http://www.napaonline.com/en/p/BEL734803). Is this OK to use? If not I can get 7mm stranded copper core spark plug wire from an aircraft parts supplier: http://www.aircraftspruce.ca/catalog/eppages/spkplugwire.php

 

Thanks.

I bought a set of universal six cylinder wires from Tractor Supply Company.  They are trim to fit and crimp on ends.  They have about 45k on them still providing trouble free service.

unfortunately don't have a store like that around where I live. NAPA is the only parts supplier that carries spark plug stuff, and even then it is limited. I'm surprised I found what i did. Best bet is ordering online for most things.

From what I have on the forum here as long as they are not carbon core on a points ignition you will be fine.

Tayto, I don't think you can use anything but suppression core wires on HEI, if your using points any thing will work.

 

As far as aircraft spruce, I'm an aircraft mechanic and instructor. I wouldn't use aircraft plug wires.

Just my thoughts friend.

While I would normally agree, these are for the rotax. Which I don't really considered an aircraft engine, even though it powers ultralights. I use to be an aircraft mechanic for helicopters but changed careers over a decade ago. The wage was poor and my heart was never really into aviation. Got to see a lot of unpopulated places in the bush and alot of the methods I still use and apply today.

I would  try them then.

I flew in P-3 Orions in the Navy during the first gulf war. And been in aviation 30 years now. Time goes too fast.
