K&N E-2999 Air Filter Product Reviews

I bought this Air Filter for my 2015 Audi A8L 3.0T Supercharged engine. What a difference it made. As soon as I put it on and started up the engine you could hear the engine actually breath better. Better performance and gas mileage. I bought 2 so I can swap them out clean one and put the other one so they can be rotated. Instead of waiting for one to dry.

To early to say, as car is having engine stripped so only used it for a week. But will be getting the car back tomorrow, so would be happy to give proper feedback in a month.

I have tried K&N Air Filter (E-2999) in my 2013 Audi A8 3.0L fuel type and I have really noticed the difference in terms of performance, initial torque and even horsepower. When you start accelerating, you can hear the air flowing through K&N filter and it really sounds good. Moreover, I can estimate the increase in hp to be around 30 hp which is great by only replacing the original air filter to K&N. Note: make sure to ask you car service provider if you are allowed to use them or not in order to not lose the car warranty. In my case, I usually remove them before the sending my car for routine checks.
