    Has anyone tried replacing the intake manifold with the 3 stage unit from the 2006 330i or X3 with the 255 HP engine? From what I've learned this is the main ingredient for the extra power, with a big increase in torque. Turner makes a kit for the 2006 325i that includes the manifold and also larger headers and cats for $4K. But I wonder if most of the increase is available by just swapping out the intake manifold?

    Thanks.........

    ........if it sounds too good to be true, usually is. The Turner kit does indeed require a software upgrade. We really like the Montego Blue first offered in 2007, but a 2006 fits our budget(?) better anyway.
