Then you can slide the new manifold into place. At this point I have already swapped over the various sensors and the fuel system from the old manifold. It should be pretty obvious. If you cant figure it out just by looking at the 2 then youre probably already in over your head and should seek out a professional to do this. Oh by the way you will need some #6 metric bolts to connect the fuel rail to the new manifold. The new manifold has no studs for the rail or for the throttle body either.
