I love the AEM Dryflow air filters. I have been using them on my car for several years now and this is by far my favorite high flow air filter on the market. I really love not having to oil the filter which makes cleaning and reinstallation a breeze. Solid contruction, great quality, plenty of sizes to fit any vehicle, and great price. Customer service is super helpful. Ordering process is easy. Five stars all the way.
