Thanks for the inputs and all the valuable information.
I've ordered BMW PE. Car is in the shop today for the installation.
Not getting the intake as of now.
But they gave me the price quote for Dinan intake add on.
the Dinan intake setup adds to the stock intake and its costing $730 (including, tax and labor). Is it worth spending this money on Dinan ??
I'm not that concerned with the performance, I want the sound :-)
