Gents! Has anyone tried making their own air intake? What I'm after is the nominal size of pipe used, the lengths and the angles involved.. as well as nipples that need to be welded on intake pipe! The idie is to go right from the cross over down to the end where the pod will sit. One thing to remember is that the outside diamter of the pipe will need to fit the inside diameter of the the pod filter adaptor. Can anyone shed some light?!
