K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's Million Mile Limited Warranty™. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter alone. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Great drop-in filter for Audi A3 that bumps up fuel economy a bit and performs extremely well compared to disposable filters.

Instant low end power boost and a throaty sound for my Audi A5 2.0T; I recommend this air filter.

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.
