540 hfm question...

[Elusive303]

Is the 540 hfm a direct bolt on for a 95 m3? and will it work with a dinan cai. heard that the euro hfm and 540 hfm are the same. need to know before I make a purchase.

Go for it, but make sure you get software to run it also. I think the dinan CAI's are 3.5" around, so it should attatch to it well. Along with software, you'll need an adaptor to connect the HFM to the intake elbow. M3Jokster sells them for $65.
