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!!

To be honest, the installation was easy. Fits as good as the stock filter. I didnt notice any change in performance.

I purchased the E-1987 air filter for my 2012 Audi Q5. Installation was easy, just needed to take the plastic air box on the left side of the engine compartment apart, swap the filter out, and put the box back together. It only took about 15 minutes. The K&N filter provides a little throatier sound plus it seems to make the engine a little bit more responsive than with the OEM filter. Haven't really noticed a change in MPG, if there is any it's negligible. Given that I'll never need to change the air filter in this vehicle again, plus with the other minor improvements I mentioned, to me it's well worth the purchase price.
