i have a 2006 xlt 5.4 v8 i was wondering what is the best fuel injector out there for my truck without damaging the engine

 

The ones that came with the engine perhaps...

 

what mods do you have and what are you trying to achieve?

 

all i done to it so far is cold air intake and exhaust but im going to put a supercharger on it, headers, e-fans, underdrive pulleys, change out the spark plugs, programmer, and wehatever else peformance parts i can do to it really

 

If you Buy the Roush IC S/C you get new Fuel Injectors new Spark Plugs and cold air intake thats sealed from the engine bay a true CAI and Some New unbelievable power (remember the old lotto commercial the guy cant get the smile off his face ya its like that)

 

PS.
underdrive pulleys are not compatable with S/C
