Product Description

The aFe POWER 31-10225 Pro Dry S Air Filter is a high-flow OE-replacement panel filter engineered for select BMW 2-Series, 3-Series, and 4-Series vehicles equipped with 2.0L engines (both gas and diesel). Featuring dry synthetic media that requires no oiling, this filter simplifies maintenance while improving airflow and filtration efficiency over stock paper filters. The three layers of Pro Dry S media and tall, deep pleats provide increased dust-holding capacity and enhanced engine breathing for improved horsepower and torque output.

Constructed with a robust 100% polyurethane boxed frame and an integrated progressive bump seal, the 31-10225 ensures a tight, leak-free fit in the factory airbox. Its washable and reusable design allows many cleaning cycles over the life of the vehicle, reducing the need for frequent replacements and lowering long-term maintenance costs. Installation is simple - remove the old filter and install the Pro Dry S element for reliable performance gains and protection.
