Just did the stage 4 upgrade.

I just did the stage 4 upgrade on my 2015 Tri Glide Ultra. Has anyone that did this switched their 103 air box sticker to the 107 sticker?. Interested to know what you did.

Thanks

When I did the Stage 1 they put the Screaming Eagle sticker on the air box.

My stage 4 kit did not increase the displacement but it was done 2 years ago. Stayed 103 w/ pistons, cams, heads, injectors, and intake, no cylinders. They're selling a stage 4 now as a displacement increase too?
