spark plug wires

I'm replacing the spark plug wires and can't source out 7mm diameter at the local shops. Do 8mm wires fit in the distributor cap holes ?
thanks

 

Not without some careful trimming, but it can be done.

7mm is available, but you're right that you won't be finding it Autozone and Pep Boys. Magnecor I think is where I'd start.

 

I have these 8.8mm from another car project that I didn't use. Will this trim job work, or is it a waste of time ?

8MM fit in mine without having to trim them.

 

On my '82 308i the wires are pertronix 7mm - 500 ohm/ft.

 

Kingsborn sells them in 25 ft rolls.

 

Thanks for the replies gentlemen, I like the idea of buying a roll and making my own. 25' sounds about the right length. Good idea yelcab

 

Just be sure to use the correct type. For stock ignition copper core is fine. If you have upgraded ignition like Pertronix or a direct fire system you want wire wound resistor wires. Using the old style copper wires with a newer electronic igniton can interfere with proper operation.

 

And I put Taylor 8mm wires into repro caps on mine. i used a large drill bit BY HAND to gently chamfer/ease the edge of each hole. I also cut the end of the wire down to the core and folded the core back on itself. Was advised to do this by an old timer. It does give you a better chance of making sure you hit the core solidly with the brass pin.
