The aFe MagnumFLOW P5R drop-in air filter for BMW 3-Series and Z3 models from the mid‑1990s (approximately 1994–1999) with 1.8/1.9L engines upgrades the factory element to increase airflow. It uses a 100% polyurethane boxed frame and five-layer Pro 5R cotton gauze with tall pleats for high flow and dust capacity. The pre-oiled filter is washable and reusable, seals with an integrated urethane bump and fits the factory housing with a limited lifetime warranty.
