I noticed the Dyna DC2-1 ignition coils smoothed my idle and pretty much everything else. They have been in there for years with zero maintenance. The materials list is inside my data sheet, which is still in the welcome mat forum. Scroll to the top of post#1. I used stainless button heads to mount the coils and terminals to avoid sparking against the mount bracket. Once installed they are more bullet proof than stock.
