2010 Ford Flex (3.5 liter, not ecoboost).
Impressed with the instructions and how custom this really is. Went on easy enough only had to backtrack a couple of times. Makes the 3.5 liter v-6 sound pretty tough (non-turbo), we'll see how it does on MPG and towing (if a few horsepower is even noticeable). Biggest concern is when it comes time to clean it and remove the filter, a lot of stuff will have to be loosened, disconnected and moved to to the tight clearance. Great value, fast shipping. Came with the bonus cleaner and oil.
