Easy install & sounds amazing!
Took me about 30 min to remove old intake box and install the AFE intake. I immediately noticed at start up, how much of a high performance sound from from the engine when rev'd. I've own my 328i for 9 years and its become actually to fun to drive again, listening to the engine when drawing out shift point in my car. Its a bit pricey, but as the old saying goes you get what you pay for. I'd recommend this to any e90 owner out there!
