Show original supplier description
The ARM S58 Intake is engineered to deliver an incredible turbo sound and unrestricted airflow for S58-powered BMW vehicles, including the G80 M3, G82/G83 M4, and G87 M2. This system boasts 3.5-inch turbo inlet piping constructed from 6-layer reinforced, high-temperature silicone, paired with large, inverted multimedia air filters offering a substantial combined surface area of 290 cubic inches. This design prioritizes a direct path to the turbochargers for optimal performance. Construction details include 3.5-inch wrinkle black coated aluminum connecting pipes, with the rear turbo inlet maintaining its full size while the front smoothly reduces to 3 inches to match the OEM front turbo size. The intake connects to the turbos via custom-designed, CNC-machined S58 turbo adapters that ensure an OEM-like fit and finish, secured with the original C-clip for easy installation and removal. Each adapter is specifically designed for the distinct OEM turbo sizes on the S58 engine. The installation process is highlighted as a key benefit, with a typical completion time of approximately 30 minutes and no cutting or trimming required. The product comes complete with all necessary components, including the filters, connecting pipes, turbo adapters, and clamps. This product is designated for Off-Road Use Only and is intended for racing vehicles.
