Post by: Jeff Grube on May 04, 2019, 10:08:22 AM

Any suggestions on upgrades to stock spark plug wires?

My dyno tuner, Ed at "The Dyno Difference" suggested that the stock wires are fine to use.  I don't remember the resistance measurement (might be 250 to 500 ohms per inch) but there is one, just measure the resistance and use the stockers, save some bucks.

I replaced wires on my ‘19 CVO SG with H-D Phat Wires for aesthetic purposes. While I cannot comment on the engine performance enhancing benefits, I can say they have noticeably reduced AM radio interference and increased AM range.

One plug boot on my Wife's FLD is damaged....want to replace with some blue Accel wires....any comments on Accel?    Apparently Harley does not make any other than stock for her bike        https://www.amazon.ca/dp/B001OMKGCA/?coliid=I3OZ1256WFX5VT&colid=1V56KIQS31QZX&psc=0&ref_=lv_ov_lig_dp_it (https://www.amazon.ca/dp/B001OMKGCA/?coliid=I3OZ1256WFX5VT&colid=1V56KIQS31QZX&psc=0&ref_=lv_ov_lig_dp_it)

Had a gift card to burn and bought SE plug wires. They look better to me. Don't know of any performance boost.

Run both Accel and the Moroso Blue Max wires 40 yrs ago on SBC's and BBC's and they ways worked well. Those wires are probably not even close to what they sale now. Never tried on Harley but a set of the yellow wires would sure look good on my bike. Let us know how it turns out if you give them a try
