I've installed the roush cai on my 2.7 badlands it's a easy installation and easy to remove the filter which also has a clear window to see the filter. It's a dry filter which doesn't need to be oiled. However, the kit doesn't change out the pipes.
All I run is 93 the best ive got on the hwy was 19.5 mpg and 21 mpg on country roads without any mods. Winds play a big factor on achieving max mpg and staying out of boost.
Took mine in for a oil change and tire rotation, my dealer advised they had the parts for the seat belt latch recall and had everything done within 1 hour. From my understanding parts are available for this recall.
I'm both a ford and jeep guy. The bronco ride on road is day and night. Larger cabinet, seats are alot more comfortable, the over all look of the bronco is badass.
