Took 15 min to install about 2 weeks ago. I can feel my car is much more responsive. And to my surprise, my X5 gains 2 MPG (my wife's BMW 330i also gains 3 MPG with an AFE drop-in filter). Very rigid and easy installation... love the product.

Great easy to install product

Took literally 5 minutes to install and immediately I could hear the difference just starting the car up. I've noticed a little power increase and a small increase in my MPG, but as with all intakes, unless it's paired with a programmer, etc, it's not going to give you a substantial gain in power. I have noticed more top end power and would recommend this product due to its low price and ease of installation.
