Stupid question maybe....lol
I may be having a brain fart but I really dont know haha
Is there somwhere on the truck that would tell me?

Its an 03 FX-4 four door 5.4

 

then its a 2v

3v started in the 2004 with the square slide in air filter...if its cone air filter it is a 2v

 

and on the air filter box it will say 5.4 3v Triton

best picture i could find..see?

 

yup you've got a 2 valve, unless you've done a swap (and there's only one we know of so far)

 

I was almost sure the 3v started when the new body style came out but wasnt 100% sure.

I am puting on a Spectre CAI and just wanted to make sure I wouldn't need any tuneing

Thanks

 

There will be a sticker under the hood somewhere, like this -

 

I've test driven a couple new 3v's and was not all that impressed. The werent broken in and all but my old truck would beat them and its not like my truck is super modded or anything.. Pretty much stock. Gryphen tuner K&n drop in that about it.

 

im not impressed with the 3vs either..anything beats the ole 4.6 tho :o

 

Yep I've beaten a few, unless they have a tuner. A tuner like night and day for those engines.

 

HI!... Ya I'm not a 5.4 3-valve fan either. Pick on them all the time with the "DANGER" Ranger... lol!

 

its all torque managements fault remove that it will feel like a different truck

 

I test drove several 05's and 06's after I sold my 2000 5.4 and I thought my 2000 was stronger than the 3Vs.

Starting in 04 they do weigh about 500 lbs more due to the stronger frame.

Now I have an 02 5.4 and the Superchips really woke it up!

 

 

check out the link i posted..where did they get that badass gray filter?!

 

Lets put say a 8000LB., trailer behind both your truck & my 5.4 3v....& hook them up from the line....you will soon realize the 3v's torque supremacy over your truck real quick!!!................
