Excellent service, Fast Shipping, Went on my 1956 Porsche 356A, Solex P4011 and fit great.
Robert Murphy, Denver, Colorado
I have now received the oil and air filters for all my cars- Range Rover Sport Supercharged, Jeep Grand Cherokee Limited, Jeep Rubicon, Mercedes Benz E430 and Porsche Cayenne S (only air filters for this one). I have used your products for a long time and am fully satisfied, so I keep the oil filters in stock for regular oil changes.
Humberto Pacheco, Costa Rica
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!
