Products are a bit pricey; I would have liked a slight reduction in price for cars which need two separate air filters (dual-turbo setups, etc). I didn't notice too much of a performance increase, but I trust that there was still some increase in BHP as K&N has a reputation for providing in other applications. Engine sounds slightly better as well, mainly when my two turbochargers are spooling up louder than before. I take this as a sign that they are receiving more air than they were before with the stock paper filters. I am also pleased with the slight increase in gas mileage, which has been approx. 1-2 MPG. Thanks
