The aFe MagnumFLOW OE Replacement Air Filter (Part# AFE31-10118) is designed to deliver superior filtration and maximum performance for your Audi A4 from 2002 to 2009. Crafted with a durable 100-percent polyurethane boxed frame, this filter offers a secure, leak-proof fit that maintains optimal engine protection over extended service intervals. Its three layers of Progressive Synthetic (Dry) Media ensure efficient dust and debris filtration, providing a longer service life and reducing the frequency of replacements. The tall, open, evenly spaced pleats increase the surface area for dust holding capacity, supporting longer periods between cleanings. Additionally, the integrated urethane bump seal guarantees a tight, no-leak seal throughout the filter's lifespan, enhancing overall engine efficiency and protection. This filter is washable and reusable, making it a cost-effective and environmentally friendly upgrade for your vehicle. Designed for easy installation, it fits directly into your Audi A4's air intake system, restoring airflow and improving engine responsiveness. Whether you're aiming to maintain factory performance or seeking improved filtration efficiency, this aFe MagnumFLOW filter provides a reliable solution, backed by premium materials and engineering excellence.
