I know this is an old thread, and I have searched the forum for the answer to my questions for a couple days. Often when n00bs come on board, like me, and ask the same old questions, it gets old.

My question is this, since I am very interested in making this 2008 intake manifold change to my 03. I have one of these intakes located, but noticed the intakes gaskets/rubber rings are a different part number.

Has someone on here done this change? Is it a direct fit on the 03 heads?

Thanks in advance for your help.

Thanks very much, you nailed it. All the the information is right here.

Looks like the throttle body is the main issue, going from 3 bolt to 4 bolt. If I had any way of giving you rep, I would. Thanks again!

I was wondering what the cam specs are for the 2011 4.7 flex, would I benefit from the HO cam?
