Rated 3 out of 5 by from Looks Great to finish off the top of yoiur heads This looks great on a engine it will fit on. On the page for this it said it would fit my bike but it does not even come close to fitting it. I just bought a 2017 Tri Glide Trike and the 107 engine is totally different. I will wait for the ones that fit to come out. They look great when they fit!!

Rated 5 out of 5 by from Bridge added style to the other side of the bike engine Bridge helped fill that gap nicely. Also, added the Screaming Eagle 10mm plug wires (black).

Why this fits 15' FLHTKSE but not fits 15' FLHXSE? They engines are the same!

Asked by: cdemczuk

Once installed is there a heat build up that would be bad for the heads& spark plugs?

Asked by: Harleyrider50
Hello Harleyrider50, You do not need to worry about excessive heat build up from installing the covers. Thank You!

Diamond Cut Edge?

Does these match up with the diamond cut edge on a stock 09 Ultra Classic?
