Product Description

The aFe 54-76301 is a Momentum dual cold air intake system built for the twin-turbo 4.4L S63 V8 shared by the BMW F10 M5 and F06/F12/F13 M6. Twin rotomolded sealed airboxes replace the factory intake components on each bank, each housing a large 7.5-inch oval Pro 5R filter designed to capture the coolest available intake charge while keeping engine bay heat out.

The patent-pending filter-to-housing interface lets aFe fit the largest filter practical into each housing without adding complexity to the installation, and CAD-designed, dyno-tuned intake tubes are engineered specifically around the M5/M6 engine bay for a precise fit. Built-in sight windows on both housings make routine filter inspection simple without removing any bodywork.

This intake suits M5/M6 owners looking for a genuine sound and performance upgrade with a cleaner, more purposeful-looking engine bay. Since reported dyno figures for this application vary between sources, I'd recommend checking aFe's current listing directly for the latest verified gains before making a final decision. California residents should note this product is not CARB exempt.
