who drives a Nissan Altima

Purchased this time on the site which I thought was for my car. My car is an 2011 Audi A6. The description showed this item was good for cars 9-11. I assumed that was they year but have been told after talking to K&N that it meant it was good for cars built September 2011 or newer. So after taking the car apart it did not fit. I got a full refund which I am happy with. I can not rate this time because it was not used. AutoAccessoriesGarage was great and helped me get the refund and explain the situation. I purchased a different air filter from their site right after I talked to them because they were so pleasant and prompt.
