I fit my cowl over the last few days. The factory makes it look so easy on the videos. I was pleasantly surprised when I started the fit. The holes for the bottom intake cover were predrilled and there was almost no trimming or sanding involved. It fit almost perfect from the start.
The oil door was a little more difficult. The factory started the trim in the top of the cowl. Didn't seem like a big deal at first but had to fit the hinge to the cowl first then to the door second. Opposit of the directions and video.
The fit of the cowl to the boot was nerve racking. The cost of failure is pretty high I'm guessing! My first trim was 1/2" and that was a little to much. If I had to do it again I would have done 3/8". It didn't fit as well as I wanted it to and I'm still not sure why. I obviously didn't have it lined up close enough. It is tough to keep it in the right place for that first cut. another nice surprise was that the front hole was cut to the final size by the factory. I wasn't expecting that.
I took extra time for the second cut and it paid off. I ended up with just under 3/8" spacing and my gap turned out very nice. It's nice to have that part of the project over. I really don't like that carbon fiber dust!!
