Does anyone know if there are any differences in the 5.4 for the 03 to 04? Im looking to get the roush supercharger kit sometime in the near future but i can only find it for the 04-08 models. Will this fit my 03 with no problems??

 

I believe the 04-08 where 3v ...and the supercharger wont fit

 

Damnn... Ok thanks

 

Well to start, 03 is a 2 valve and the 04-08 is a 3 valve so the heads are different so the intake is different as well, I can't see that kit working with out a custom intake
