Is there any need to change the spark plug wires as a matter of general maintenance? Bike is a 2003 Heritage with 53,000 miles on it, with the original wires, and original coil.

Not having any problem really, just wondering if there is anything to maintain or improve in this area.

I see Harley offers screamin seagull 10mm wires for it, but nothing comes up for ignition coils anymore, at least not online. I know they used to offer some for it.

 

Wow, not nearly as active over here as the engine forum...

I ran the bike in the dark tonight, and the rear spark plug boot is arcing to the base of the plug. I will seek out replacement wires tomorrow.
