First choice
I have fitted these to every car i have owned for the past 15 years. Foe me an absolute 'no brainer'; more power/response, improved MPG and pays for itself in three years of ownership.

More throttle response improvement than expected.
I installed two of these in a Cayenne GTS and the throttle response is far better from low revs, in particular. I did not expect such a dramatic change. I am delighted.

End of replacing air filter
Achieving slightly better fuel consumption as well as not needing to buy replacement air filters for my car. What's not to like.

As always, a fantastic product.
A very snug fit, but a perfect fit nonetheless. By snug fit, I mean that the Audi Q7 design makes changing your filters a very involved process that can take a hour or more. Not the fault of the filter. I have been using K&N filters for years and have always been pleased with their performance. After having these filters in my Q7 for about a month, I have seen a slight increase in my gas mileage, and a big increase in the throttle response. The gas mileage improvement, at today's gas prices, should cover the cost of the filters within a month or two. I will also be saving money by not having to purchase the expensive paper filters anymore which can cost as much as the K&N filter. The only downside is that paper filters do filter significantly better than the K&N, but at the expense of fuel and power. What side effects, if any, is a result of those micro particles getting into my engine (maybe shortens the life of the A/F sensors or other emission sensors) I have yet to experience first-hand. At least that I am aware of.

Great upgrade for my Touareg
I bought this while it was on sale. After installing, my 2011 Touareg 3.6 FSI accelerates better from a stop and the engine sounds quieter during acceleration, in a good way. Now the car feels quick on its feet! Very happy with the product, will pay attention to the fuel economy in the long term and provide update.
