Drop-In High-Flow Air Filter

The HPS Performance Drop-In Air Filter (HPS-457374) is engineered to be a direct replacement for your vehicle's OEM engine air filter, offering improved performance and longevity. This enhanced airflow can contribute to better engine efficiency and responsiveness. The filtration media is crafted from specially formulated, sensor-safe oiled cotton, designed to effectively trap particles as small as 5 microns. This media is encased between durable stainless steel mesh, which helps maintain the filter's rigid pleats. Being washable and reusable, this filter offers an environmentally friendly alternative to disposable filters and can be serviced every 30,000 miles with the HPS Performance Air Filter Cleaning Kit. Designed to meet or exceed Original Equipment (OE) specifications, this HPS air filter is built for durability and is backed by HPS's 10-year limited lifetime warranty. Installation is straightforward, typically requiring only a few minutes and minimal tools, depending on the specific vehicle application. The filter is compatible with a range of Subaru models, including the Ascent, Crosstrek, Forester, Impreza, Legacy, Outback, and WRX, covering various engine sizes and model years from 2017 to 2024.
