I have already chosen to use the stock airbox with a K&N drop in, but my question is has anyone looked into making just a replacement tube from the TB to the OE box to eliminate the ribbed tube?? I remember in the Hemi world it was the ribbed tube and the resonator which gave all the restriction in air flow and a few companies came up with a replacement tube to replace those parts and increase airflow, or at least smooth it out.:dontknow: Just checking, didn't see anything on a search...........I was thinking Tony or justin amybe:dontknow:
