Hi Narsh.I have the Mac straight shot.It came with the bigger billit mass air meter.It makes a all around noticable difference.Compared to the stock rubber hose.If you look in the stock piece you will see a restrictive section 4 inches from the throttle body.The stock mass air is weak too.Ford is known for restrictions on lots of their parts!I read a test on hooker long tube headers gave 37 more hsp than stock manifolds on a 4.6! But they aint cheap.nor is the install.
