PROFILE
The ARM S58 Intake will make your G8X BMW sound amazing while providing unrestricted airflow to your S58's turbochargers. The ARM S58 Intake delivers the shortest distance possible between the high-flow filters and the turbos. Coupled with the largest turbo inlet piping available, and you have the ultimate performance-oriented intake solution for your S58-powered BMW!
CONSTRUCTION
The ARM S58 Intake utilizes extra-large 3.5" turbo inlets made from 6-Layer reinforced high-temperature silicone. The high-flow multimedia air filters are inverted to provide more filter surface area than standard conical air filters. The total surface area of the ARM S58 Air Filters is 145 cu. in. each, making the total combined surface area of both filters 290 cu. in. 
The filters connect to the turbo inlets using the 3.5" wrinkle black coated aluminum pipes. The larger rear turbo inlet maintains its 3.5" size all the way to the turbo, while the front turbo inlet is gradually and smoothly reduced to 3" to connect to the smaller OEM front turbo. 
Instead of crudely connecting to the turbo snout, like many other S58 intake systems, the ARM S58 Intake connects to the turbos utilizing our CNC machined S58 turbo adapters. These turbo adapters are designed in-house to allow for an OEM-like fit and finish that exceeds the quality of the OEM plastic connections. The ARM turbo adapters are secured to the turbos using the OEM C-clip, allowing them to be easily installed and removed. Each turbo adapter is designed independently to fit the different sized OEM turbos on the S58.
