How difference between H/O and Regular Ecoboost?
Look for this tag on front of engine head. The VEP on the right top denotes Valencia Engine Plant.

How difference between H/O and Regular Ecoboost?
I think a few people have gotten of track posting about V8's, this is a 2.3 Ecoboost thread.

Here's a great video to watch from the Ford engineers that designed the HPP.

PP1 rear spoiler on convertible?
When I had my 2014, I installed a California Special wing on it. Looked great in my opinion. I know it's not an S550, but I was told I couldn't install one on my S197. Surprise, it works and looks good too. P.S. I did drill holes in the decklid.

Can you add seats to Mach 1 Rear Seat Delete Spec.
You may be better off finding one with the rear seat already in it. Just my opinion.
