⚙️ How it works
This intake replaces the restrictive stock airbox. Thanks to its high-flow filter and enlarged duct, it allows for better intake of cold, dense air to the engine. The result: more efficient combustion, increased power and torque, and reduced turbo lag. The CTS Turbo system is designed to maintain laminar airflow and reduce turbulence, maximizing the performance of the B58 engine.
