I'm putting together my own intake for my 98 a4 1.8 and am wondering if i will need an MAF sensor adapter for it when i put the new intake on. Also on the stock airbox their seems to be alot of sensors and wires going into the airbox and coming out of it, what will i need to do with thos becuase i'm not sure what to do with them with the new intake. The old airbox will be taken out .
