Just picked up some fat Screamin Eagle spark plug wires for my '05 Dyna. There isn't any noticeable damage to my existing aftermarket ones but they look pretty old and I just replaced the spark plugs so figured why not. Just bought the bike in January and it had 25k on it when I bought it.

Anyone have the Screamin Eagles on their bike? Any difference when you changed them?

 

I had them on my Train, couldn't tell any difference. They did look better though.

 

Yea I figured. They had some ugly red aftermarkets on there. I got the black wires today.

 

But the red wires will make you go faster

 

yeah, the color

 

Its true the red ones do make you go faster. Wow what a difference they made. But the guy at the hd dealer in waco tx said if you leave them in the sun a lot they will turn pink.

 

Does the bike slow down once they've gone pink? Best keep mine out of the sun.

 

I have them on my Iron and as expected, there was no difference from stock.

 

They added a good 10 HP and 20 MPH to mine.

 

Yup, mine are orange, the color is about the only noticeable difference.
