Upgrade your vehicle's air intake with this high-performance AIRAID filter. It's a universal, clamp-on style filter with a round tapered shape, measuring 4 inches at the flange inner diameter, 6 inches at the base, and about 4.625 inches at the top, with an overall height of 9 inches. It's designed to fit a wide range of custom or aftermarket intake setups. The filter uses a superior, high-flow cotton gauze media that lets your engine breathe easier, which can lead to noticeable improvements in horsepower and throttle response, and even better fuel economy. The best part? It's washable and reusable. Just clean and re-oil it with an AIRAID filter care kit (sold separately), and it's good to go again – saving you money over disposable filters. It's hand-built with quality materials and backed by a lifetime warranty, so you know it's built to last. A great mod for enthusiasts looking to boost performance without breaking the bank.
