BD Diesel bdd1045844

The BD Diesel L5P Screamer turbo is a drop-in replacement for 2017–2021 GM L5P Duramax 6.6L engines that raises airflow and power without a major overhaul. Built using OEM housings machined to accept larger compressor and turbine wheels, it improves flow up to 80 lb/min while retaining strong low-end drivability. The screamer installs with stock emissions gear, includes an intake horn, and delivers higher airflow and lower exhaust gas temperatures when used with proper supporting modifications and tuning.
