Spark plug wires interchangeable?
So I got a pretty wild shock when touching the coil end boot of one of the plug wires on my 95 FXDL. Time for some new ones!
First choice was Screamin Eagle ones or just stock HD but the ones for my model/year are hard to get hold of.
Apologies for the dumb question but are there SE/HD leads from other years/models that will work just fine? Or am I going to need to go aftermarket.
edit for clarity: the only reason I was touching the wire was Id had them off to test the coil resistance and was sat at lights and just double checked Id plugged them back on tight.

I like the connection at the coil to be straight boots and at the plugs 90* boots...

Thanks. The SE leads that fit are 10mm, presumably that means 10mm Leads are ok too?

What makes them specific to a model? For example what is the difference between a 10mm wire on a 95 Dyna and a 2010 Dyna?

I'm sure it has to do with the type of coil connection (the type of boot) I deal in older bikes so I wouldn't know anything about the 2010 models... And for our older bikes you don't need a 10 mm wire... Waste of money...

Its nice to see a post thats within the last 5 years instead I ve been reading threads over 10 years ago. Whats up? Where is everybody?
I just now ordered some plug wires off Amazon. I know Im of the future lol, theyre for a sporty but thats the best I could find for my older Harley. The 8 mm red. 15.00 Im hoping they work good. The current ones look very old and the paint is coming off. Plus there is a random misfire. Which could be around 50 different things 😀. Something to keep me busy through the fall. Hello out there. Is anybody listening. lol

On the few times that I called, I actually spoke to human that is on location of their warehouse. Fast shipping, fair pricing. I can even type the OEM harley part number in the search window and the non oem replacement (compatible aftermarket) parts will come up.
If plugs and wires don't cure your miss, remove the round cover and check out the nose cone cam sensor. If yours is original it can be demonstrating early signs of failing. They have a "history".

I've used Dennis Kirk with good results and also Parts Giant who have provided me with excellent customer service.
I make my own plug wires as a rule.. Accel wire kit for older Chevy hotrods work well.
