Product Description

The aFe Power 51-12922-B Magnum FORCE Stage-2 Cold Air Intake System is a performance-oriented upgrade crafted for turbocharged BMW models equipped with the 2.0-liter B46/B48 turbo gasoline engines - including the 230i, 330i, and 430i family across select model years. This Stage-2 intake replaces the restrictive factory air system with a high-flow design highlighted by a tall 7" Pro DRY S dry synthetic media filter and a precision CAD-designed roto-molded intake tube that outflows the stock intake for improved airflow and throttle response.

Featuring a lightweight vacuum-formed plastic cover with an auxiliary air inlet for cooler air capture, the 51-12922-B not only enhances engine breathing but also maintains a stealthy under-hood look. The washable and reusable Pro DRY S filter simplifies maintenance while providing strong filtration performance, and a urethane plug is included to block the auxiliary inlet if desired for intake temperature tuning. Installation is straightforward with a direct bolt-on design that uses factory mounting points and includes all necessary hardware. Estimated airflow improvements and gains of up to around +12 HP and +12 lb-ft of torque make this intake a solid performance upgrade for BMW enthusiasts.
