Nope....'99-'04 The only difference between the '99-'00 and '01-'04 is that the earlier heads were Winsors and the later heads were Romeo.

You'd know what it meant if you didn't have it every time you got in the car

NPI owners usually cry in their sleep due to it.

They were a new improved h/c/i system put on the 99+ 4.6s from the factory. This is the reason 99+ make more power than the 96-98s.
