If you ignore the bull-advertising hype. I like the intake. I made something similar on my engine with the tubes and scoops and it worked out really well. It was just high maintenence, every piece of dirt, mud, sand, bugs, children would end up clogging the filters I had in mine.
I'm confused as to where the MAF sensor goes in that intake. If it moves it directly in front of the throttlebody that could help throttle response, a while back I mounted my old 4.3L's MAF directly to the throtleebody and it really helped throttle response
EDIT: saw the install instructions. The MAF does go in front of the TB, could be interesting
