    Whats the difference between the passenger and drivers side? Im holding one of each and they appear to be 180* mirror images. Is there something we are missing?


    • The only difference would be the coolant cross over would be different on the passenger side which makes it slightly different then the right side.

    Is this gasket only for the passenger side only or does this fit on both sides? Is there a part # for the driver side?


    • This Ford Intake Manifold to Head Gasket will only fit the passenger side. Unfortunately I am not able to get the part number for the driver side. Ford has them labeled as the same part number for both sides but from experience these gaskets are side specific.


    Helpful (0)

    Does this also work as the driver side or would I have to buy a different product to replace the driver side too?


    • There is also a driver side gasket they will differ from this passenger side gasket. Unfortunately American Muscle does not carry the driver side, it will have to be sourced elsewhere.

      Not the correct part for 01.

      Bought this for my wife's 01 when I replaced the intake. It should have two holes in the end for the bolts but only has one. Ended up finding the correct set at Auto shop for 19.99. If you're looking for an 01 don't waste your money this product won't work and is priced too high as well.

      Ford Intake Manifold to Head Gaskets

      You really can't get a better quality gasket than this. They are very well made and a high quality product. I installed a pair of these gaskets along with a Stage 3 Ported and Polished Professional Products Typoon intake and the fit perfectly. Absolutely no leaks. I highly recommend these gaskets.

      It works

      At first look it looks completely fine but you look closer you'll notice that it hasn't been cleaned up after the molding so there is like little praises of plastic in the runners
