I installed a AEM air intake on my ford expedition 4.6 Lt 1998. The air intake is supposely for a 5.6lt expedition. After a while my air intake started making a weird loud noise and i cant figure out what it is. Has anyone had this problem? I know is the intake becuase i installed the stock one back and it stopped making that weird loud vibrating noise. I dont know what to do i paid 400 for the air intake.
That it back and get the one for the 4.6
Its hard to diagnose the problem without hearing it for myself. An air intake on a gas engine that is naturally aspirated (meaning it takes air as it needs it, not forced into the engine) I wouldnt think that it could be anything too harmful More then likely it is loose on the intake side of the carb and is vibrating. If you can find a way to make that tight, maybe use a foam strip as a gasket (at any hardware store or even walmart) and tighten it onto that, hopefully you can save from having to get rid of it that way Also make sure youre mounting is all tight any vibration will make noise.
