Has anyone installed an intake performance chip on E60? if yes, what is the result on outcome of Gas Consumption and increase of HP rating.
I am thinking of installing one on my 2007 525XI but want to make sure if worth it

You're kidding right? This seems like an even less sound idea than the "Tornado" you can get a Walmart. Please don't do this

Remove your charcoal filter (located in the top portion of your airbox)
Replace OEM filter with BMC or K&N
Get RPI scoop.
Those are the your best options. Proven gains.

You should note a pretty evident difference in throttle response with the BMC filter, the oem filter is pretty restrictive. The RPI scoop really is just a nice funnel for you airbox at highway+ speeds.

Besides Dinan, are there any quality cold air intake systems?
Another forum mentioned the possible need to do a software upgrade after CAI installation to override the computer's need to adjust the fuel due to higher O2 intake--any comments?

Cold air kits don't work. It's a joke that they are even called a CAI. They are sucking hot air from under the hood. The stock set up is good and draws air from the grille. That is cold air. I know there are a lot of fans of the RPI scoop, but $99 for a piece of plastic is a little too much. I am going to play around and make my own out of aluminum.
