The aFe MagnumFLOW Pro 5R drop‑in air filter fits select Audi (1978–1991) and VW (1972–1985) models, replacing the stock element with five layers of cotton gauze media for increased airflow and performance. Constructed with a polyurethane boxed frame and deep pleats, the washable, reusable filter improves dust holding and features an integrated urethane bump seal to ensure a tight, leak‑free fit in the original housing for extended service intervals.
