Product Description

The aFe 54-31662 Magnum FORCE Stage-2 Cold Air Intake System with Pro 5R oiled filter is a high-flow performance upgrade designed specifically for the 2008-2013 BMW M3 equipped with the V8 4.0L S65 engine. This Stage-2 intake replaces the restrictive factory airbox with a precision-designed intake tube and high-flow Pro 5R filter media, delivering significantly improved airflow and throttle response. The washable, reusable five-layer oiled filter provides superior flow while maintaining excellent engine protection.

Installation is straightforward with a direct bolt-on design that uses factory mounting points and requires no cutting or drilling. The system includes a durable powder-coated heat shield to help isolate intake air from hot engine bay temperatures and direct cool outside air to the filter. With improved performance and enhanced induction sound compared to the stock intake, this intake is a solid upgrade for BMW M3 enthusiasts. Fitment is confirmed through 2013; coverage beyond these years is unconfirmed at the time of listing. This intake is intended for performance use and may not be emissions-legal in all regions - always verify local regulations prior to installation.
