Stealth STR Drop In VGT Turbo CPS200143 | 2017-2023 6.6L Duramax L5P

Take the performance of your diesel truck to the next level with this Stealth Performance Turbocharger. Featuring upgraded billet compressor and turbine wheel technology, this turbocharger is engineered to deliver improved airflow, faster spool-up, increased efficiency, and enhanced durability while maintaining factory-style fitment.

The advanced rotating assembly combines a lightweight billet compressor wheel with a larger high-flow turbine wheel to provide excellent throttle response, improved boost characteristics, and lower exhaust gas temperatures under load. A ported exhaust housing further improves exhaust flow and reduces backpressure for enhanced overall performance.
