Fifth vehicle equipped with K&N filter. No Complaints. Just perfect.

I drive my 2005 VW Passat 1.8 all over the Midwest for work. My average highway mpg increased well over 10. Before, I was lucky to average 27 mpg at 70 mph. After replacing old paper filter with the K&N, I've easily reached an average of 30 mpg, even in cold weather. Very impressed.

On our cars (Volkswagen / Audi 1.8T Motors) Upgraded air filters wont give us any more power then we already have. It's just a fact. But if you need an air filter why not get one that you don't have to replace every time and could just clean and re use? K&N is one of the best filters out there period. I'm a real person and wasn't paid to say this. I was going to get an (brand name) but they don't have the same guarantee as K&N. It also came a lot faster then I was expecting it to.

I got this for my 2006 Audi S4, and it's a perfect fit. For those that are wondering / hearing that the K&N filter doesn't fit in the stock air box on the B7 S4, it does indeed fit, but it helps if you install it in a certain way. I tried dropping it in top first and pushing the bottom edge in, but I couldn't make it fit. But when I tried the other way - inserting the bottom first and then squeezing in the top edge, it was much easier. The top edge of the box must have more flex or something. Considering how difficult it is to replace the filter, and how little room there is to work around the engine, I am thrilled that I can leave the K&N filter in there for 50k miles if I want. Well, maybe I'll check at 30k. I recently went out and purchased K&N for all my other vehicles.

The overall experience of purchasing and receiving my K&N air filter was truly quite simple. I have always used K&N air filters in all of the vehicles that I have owned and I will continue to do so based on price, quality, reliability and dependability.
James Kehoe, Houston Texas
I am a long time user of K & N filters and find them to be superior to other filters on the market. Better engine protection and better engine response is what they deliver.
