I have purchased a non-Ford "updated" intake manifold to replace the
cracked and leaking original intake on my 1996 GT.

The part is American-made and seems to be of high quality, and it only
cost a fraction of the price of the Ford part.

QUESTION: Has anyone had any experience with these updated intakes? One
thing in particular: This new intake has rubber "O-ring" style gaskets
molded into the top and bottom of the intake. Are these sufficient to
seal the intake to the rest of the engine, or do I need something else,
like Permatex or something?

Any info will be much appreciated. THANKS!
