not a upgrade for the 4.0
the good i noticed a very little bit of power gain with them not enough that's for sure
the horrible there is no mpg gain at all in fact it did a hell of a lot worse then my stock injectors i already swapped back to my stock and trade my friend for another set of stock 4.0 injectors i would say try the neon injectors first before the mustang ones because i got worse mpg then my 1500 ram with the 5.9 if i knew this before hand i wouldn't have paid ten bucks but i will say the guy himself got them to me fast with no problems so i will give him a 10/10 on delivery but the product it's self i would give it a 0/10
