Delivery was fast even with standard shipping. Install was a little tricky but not because of the filter but because of my vehicle (2011 Audi Q5 3.2 V6 Quattro). The screws did not align exact with the housing but nothing a pair of pliers didn't fix by bending them just ever so slightly. Other than that, I love the filter. I am unsure if this added any more horsepower but I didn't notice a little more pep and get up and go after the install. Fuel economy seems the same but I hadn't been recording the mileage. In conclusion, I am very satisfied. P.S. MAKE AN AIR INTAKE FOR MY VEHICLE AND I'LL BUY IT!!

Fits like a glove, instructions were almost perfect. I believe I have a slight gain in acceleration and gas mileage. All my cars have always been equipped with K&N filters.
