The ARM N63TU3 Intake is an intake system for the third generation of BMW's N63 engine (N63TU3/N63B), found in the M550i, M850i and 750i. It is designed to improve airflow and throttle response. Installation needs no cutting or drilling and takes about 30 minutes.
The intake runners are 6-layer reinforced silicone couplers. Each coupler has a 3" connection at one end for the factory turbo inlets and widens smoothly to 3.5" at the other end, where the filter attaches. Silicone lets the runners pass through the strut braces, which stay in place, and prevents the wear and rattling seen with aluminum runners.
The kit includes two ARM Dry Air Filters made with multiple layers of filtration media, including a high-flowing synthetic fiber layer that captures small particles. Each filter has 145 cu. in. of surface area, for 290 cu. in. combined. The filters sit at the front of the engine bay, away from engine heat, where fresh air comes in from the OEM air ducts just below them.
