Thanks RB. So heres why I ask if i look at ECS for 4.8 vs 4.6 they list the same part number for the black hood vents but only show the Titanium version available for the 4.8. The Titan ones look so much better there and had friend shoot me the pics of his 4.8 and they do appear to be a different shape.

EDIT: I searched differently in ECS (hood vs grille menu) on the 4.8is and they did note in red that the kidney grille is ONLY for 10/2003 and beyond but no such disclaimer on hood grille. Weird and they dont list the black piece as an option in that search.
