Product Description

The aFe Power Magnum FORCE® Stage-2 Si Cold Air Intake System (Part #54-81012-C) is a premium performance upgrade designed for BMW 128i, 325i, 328i, 330i, 335d, and 335i/335is models equipped with the 3.0L inline-6 engine (N52/N53) from 2006 through 2013. This sealed intake system replaces the restrictive factory airbox with a larger high-flow Pro 5R pre-oiled filter and a dyno-tuned roto-molded intake tube, delivering up to ~56% more airflow for improved engine breathing and response.

Featuring a one-piece sealed housing that draws cool outside air through dual "kidney" grille auxiliary ducts and a striking carbon-fiber-look under-hood cover, this intake not only boosts performance but also enhances engine bay aesthetics. Installation is a direct bolt-on using OEM mounting points with no cutting or drilling required. The system is engineered to improve throttle response and offer gains of up to ~+12 hp and ~+16 lb-ft of torque in optimal conditions. Certain applications may be 50-state exempt where CARB compliance applies (see EO# D-550-38).
