Throttle body gasket
 

04 5.4, I bought a new throttle body and it did not come with a gasket, upon looking for one i see this round one , i take it theres a groove it goes down into on the intake ? But the bottom of throttle body looks like it takes a square bore type paper gasket. The square bore gasket shows it fit only the 4.6 motor, but it does come up like on amazon as fitting the 5.4 . So which gasket do i need ? Both or the round one only ?

The gasket for the 5.4 is the round one on the right, it fits into the intake side.

Do not use both. Stick with the round one.

Right on,Thanks !
