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.

This is not my first K&N product. I have always used them in all my cars (from 3 different Corvettes through Audi TT and just about everything inbetween). Always had great service from them, parts always fit like a charm, and they work and sound great. Would recommend them with no problem.

Installation time and procedure in my Audi was exactly as stated. No surprises. Noticeably improved throttle response with the K&N cold air intake versus the stock airbox. Definitely recommend this upgrade.
