ive got the volant intake im not sure if its the 2.7 ive had it on there for a few years. I love it! i bought the powercore filter for it. it sounds fantastic, better then the K&N IMO and its a legitmate CAI it's enclosed, the air hole is on the side where the air can come it yada yada. dont know if you have already read my opinions on it in your search but its been one of my best purchases for the truck so far.
i have a video and pic in my build thread below if you want to hear it
