Hi all-
My buddy 2003 GT/4.6 is running a little ruff/ sounds off. He took it to the dealership and they stated air is escaping his manifold. Is this common? What is the fix?
Any aftermarket replacement that is smog legal? How much power will he gain going with a aftermarket one. It is all stock right now.
Kind regards,
Gary
