The aFe MagnumFLOW Replacement Air Filter with Part Number AFE21-91040 is engineered for high-performance automotive applications, offering a combination of advanced filtration technology and ease of maintenance. This filter features three layers of progressively finer mesh synthetic media sandwiched between a durable polyurethane top and base, ensuring maximum airflow while effectively capturing dust and debris. Its high-flow, oil-free conical design provides a significant boost in engine intake efficiency, contributing to improved horsepower and acceleration.

The pliable polyurethane flange, equipped with integrated bumps, guarantees a tight, leak-proof seal during operation, maintaining optimal filtration performance throughout its lifespan. With a filter efficiency of 99.2%, this filter offers outstanding protection for your engine*s intake system, helping to prevent harmful contaminants from entering and causing damage. Compatible with a variety of automotive applications, the aFe MagnumFLOW filter is a reliable choice for enthusiasts seeking durable, high-performance filtration. Its precise dimensions and robust construction make it suitable for vehicles where maximum airflow and filtration are priorities, ensuring your engine performs at its best under demanding conditions.
