Hello guys, I've got a 05 5.4 that im wanting to do a few things to such as a programmer cold air, exhaust work, basically all the easy stuff under 500$ I was just looking for advice on what y'all have used and experiences? So far I'm looking at a spectre cold air intake, either the hypertech max performance or edge evolution CS or CS2 programmer, also I was wondering about a throttle body spacer I have been reading and some forums say they help with the low end and some people say they don't do anything and to not waste the money. Any info is appreciated!
