MST Turbo Inlet Kit – BMW B58 G-Series/Toyota Supra A90 3.0L

MST's Turbo Inlet Kit for the B58 engine eliminates the restrictive OEM plastic pipe and turbo muffler, replacing them with a high-flow, heat-resistant silicone design. This upgrade increases airflow, improves turbo response, and enhances power delivery—all while retaining the factory airbox. Ideal for daily and tuned setups, no tuning is required.
