I'm a former Dinan fan before I realized where they were cutting corners and reselling stock pieces, and since more aftermarket manfacturers have come into the playing field, there are cheaper and more efficient alternatives...but each has its tradeoffs as well. If you've got the 4.4, Dinan sells an intake manifold that is nothing more than a factory pre-VANOS manfiold and/or the same one used on the 4.6 motor. 540 and 740 owners have done this mod plenty of times, but it appears not many X5 owners know about this. I got mine from a guy who wrecked his 740 for $50 shipped, otherwise you can find them all over junkyard websites like Car-Part.com--Used Auto Parts Market.
