A dude at my jobsite had a rental 2011 xlt from the airport and I looked it over and noticed a few things right off the bat that I thought to add to my 2010. The hood gasket is completely different and is form fitted to the crevasses of the hood, I'm guessing for a better seal. I've got more dust in my engine bay than I'd like and I may add this. Any body know what else this might serve? Also, the underbody air scoop is larger and seems to look more like a body part, rather than something hanging down from the engine. I might add this too if it helps because it looks more finished. Can the Tasca dude let me know how much this stuff is and if it is compatible.

 

Its all about noise reduction I figure...
