Is there any benefit to better plug wires? I did a little reading and some say that Harley will not run with aftermarket wires?

 

IMO, I'd just stick with the stock wires.

 

But you can get them in pretty colors!!!

 

Is there any truth to the signal that is sent back to the ECM across stock wires?

 

I bought some Red ones for my scoot. Made the idle a little smoother..

if it ain't broke....

 

I run the Taylor Thundervolt wires and believe in good wires.

 

I have always believed in Taylor wires myself. I haven't had a truck or car without them in a long time. But I read somewhere that there maybe some problem with running aftermarket wires on EFI Harleys because of a "signal" that is returned via stock wires. Didn't make much sense to me, so that's why I'm asking.

 

I run the screamin eagle 10 mm wires and mines fine my stock ones went to hell at 10000 miles and mines efi

 

I think with the newer bikes resistance of plugs and wires are critical for the ion sensing knock sensors to work.
