I've been a member for a while but due to my position this is the first time I've posted. I've always found FTE very useful. I'm glad to finally find a site that isn't polluted by Imports or GM. Occasionally my 2004 FX4 makes a slight knocking sound at start-up. Is this a charateristic of the new 5.4? When I return home I have some new parts waiting. Does anyone have an opinion on GIBSON Super Truck Exhausts / Headers? Which Cold Air Intake System Provides the best PERFORMANCE / Visual ehancements?
Hi and welcome to FTE! Your best bet would be to ask this question in the 2004-2006 F-150 or the 5.4L Engine forum. This forum is for introducing yourself.
