Absolutely love the chrome-trimmed K&N air filter! It adds a lot to the overall excellent look and performance of my old but clean 88 Porsche 911. Thanks for providing such a great product, timely and inexpensively. I looked in all the auto parts stores in Albuquerque, but they had nothing comparable for that price in stock. I appreciate being able to order harder-to-find specialty items online at less than retail. Thanks!

Nice product!  I own a 2001 SAAB 9-5 AERO with 128,000 miles and just purchased my first K & N filter...very impressed.  After 2 tanks of gas I'm getting about 2 to 3 more MPG's (city) and the performance...wow!  Even though I never believed it...Aeros are reportedly faster than a stock porsche 911 of the same year.  However, after replacing with the K & N filter, I'm a believer!  Not sure how much horsepower I've gained but the car is much much more responsive and will flat put you back in your seat if you punch it!  I never thought an air filter would make that big of a difference, but it did.

This is the 5th K&N filter that I have installed on my vehicles. They are high quality and fit perfectly. My Porsche filter finally failed after 20 years. I just sent them a picture and a new filter showed up in several days. Great customer service!
