Those still won't fit an '09. The body panels are different on 2010+. The bodysides are curved not flat.I think they are different. Look for 13-14 California Special side scoops. They should fit.

Those are the same Ford scoops I have on mine. I’m pretty sure the mention of CS is more marketing than anything else. If you go to a Ford dealer, and order side-scoops for your 2011-2014 Mustang, you will always get those scoops. No mention of being a CS version is needed.

Whish style are youblookibg for?I don't know if those will fit, but I know the ones for the 05-09 are spendy. I have an 07 GT/CS and need the left side. I can't find only one and two are a bit out of my range at the moment
