aFe Magnum FORCE Stage-2 Pro 5R Cold Air Intake 54-12922-C – BMW 230i / 330i / 430i (B48)

OVERVIEW

The aFe Power Magnum FORCE Stage-2 cold air intake replaces the factory airbox on the B46/B48-powered BMW 230i, 330i and 430i. A CAD-designed, dyno-tuned roto-molded intake tube feeds a 7" conical filter, flowing 350 CFM at 7" H₂O for dyno-tested gains of up to +12 horsepower and +12 lbs. x ft. of torque.

This version pairs the pre-oiled, washable Pro 5R filter with the carbon fiber look cover, moulded from lightweight vacuum-formed ABS plastic for a purposeful under-hood appearance. An auxiliary air inlet in the cover feeds additional cool air, and a urethane plug is supplied if you prefer to block it off.

All clamps, couplings and hardware are included. The kit is a direct bolt-on that requires no cutting or drilling of factory parts.

TECH RESOURCES

Additional Parts Required

• None. aFe Power specifies no additional hardware, tune or fluids for this intake — it is a direct bolt-on kit that requires no cutting or drilling of factory parts.
• Installer-supplied: basic hand tools, including a T-handle or driver for M4 Torx screws and a nut driver for the hose clamps.
• Optional service item: the Pro 5R filter is a washable, re-usable oiled cotton-gauze element and must be re-oiled with aFe filter oil after each cleaning.

Installation

• aFe Power 51-12922-B / 51-12922-C / 54-12922-C installation instructions (PDF)

Notes

• The previous version of this listing described a Pro DRY S filter; aFe’s catalog and installation instructions specify the oiled Pro 5R element (24-90096) for P/N 54-12922-C, and the Pro 5R spec is used above. Does NOT fit Convertible models. Year ranges above follow aFe Power’s current installation instructions rather than the wider ranges previously shown in this listing. 2016 330i / 330i xDrive coverage is for non-US-market cars. Confirm fitment with Speed Logic before ordering.
