I had the AEM cool air exchange installed in my car years ago and have loved it. The air filters I have ordered have all been serviceable and performed well. I have ordered them for several years and they have always been shipped promptly and arrived in good shape. The website is informative and easy to navigate, and the prices remain reasonable. It's an A+ from me, as I could not give a higher recommendation to both your products and your service. Thanks so much!!
