I was very pleased with the way K & N was able to match the type of air filter that came with my 32 Ford Coupe with their product and delivered it quicker than I had expected. The new filter fit perfectly and my car runs like a charm. I had the same great service with the other two filters that I purchased at the same time for different model hot rods.

Thank you for manufacturing such a great product. The filter fit perfectly on our 66 Shelby Cobra, and looks great. I believe I can feel the increased performance after installing your filter. Thank you again
