i recently replaced my stock spark plug wires w/ se 10mm wires and wondering if what would be a good coil to upgrade to? everything is stock on my night train except for the exshaust,V&H large radius 2 into 1, s/e race tuner,s/e heavy breather intake...the bike has 3400 miles on it

Hi denium...welcome aboard
Gotta ask why you replaced your stock plug wires at only 3400 miles...and assure you that based on the mild modifications you've described you'd have nothing to gain by up-grading your stock coils. Well...nothing you'd see hear or feel anyhow...unless,of course, you've been having some problems with your stock syst'm that I would ass-ume is still under warranty on a bike with those few miles

BTW...it's my understanding that ECMs are sensitive to plug wire and coil "up-grades" etc and others here may have some warnings for you...as far as that goes.

Yep Ken hit it on the head.
I've got to ask why you think you need more coil, it's is easer than telling you why you dont.

I have to side with the majority on this one,I have a ton of engine mods & still run the stock coil.

Just got my first HD 07 Dyna Super Glide, Installed the Ness Big Sucker, ThunderHeader, and PC III. My 68 Firebird 400 responded so well to to the MSD Dist/Ig Box/coil combo that I wondered if I should do something with the Dyna ignition to pump it up before I get the bike dyno tuned?
