all that is needed is adapters to use the 4.6 intake.

Do you have to use a 4.6 intake?

myillwillinc · 02-28-2007, 09:26 AM

no, but the 5.4 intake is huge as is the lightniing blower. both wouldn't fit under a 4in cowl hood. what i meant by that comment is that i didn't have to change anything to make it work in my car. i got a set of adapters and the rest is stock 4.6/5.4 parts. it was a ton easier then the magazine made it out to be.

what part of the fuel is changed?
whats the gains of you changing your 4.6 to a 5.4 so far?

myillwillinc · 03-09-2007, 05:04 PM

you don't have to change your fuel system if it is stock. but i would recommend 24's. the torque is amazing, it feels like it will never stop till u let off the pedal....
