The PPE Carbon Fiber Turbo Inlet Upgrade addresses the undersized, flow-choking section of the factory LLY turbo inlet. Maintaining a large 4-inch diameter all the way to the turbo flange, it enhances turbo efficiency and increases torque. The factory CCV port is preserved by the threaded-on aluminum CCV adapter. For optimal efficiency, the factory air cleaner outlet tube is trimmed just after the second bend. A specially designed free-flow silicone coupler seamlessly connects the factory tube to the PPE Carbon Fiber Inlet, promoting smooth airflow. Additionally, the plastic turbo resonator is removed to declutter the engine bay. The PPE Turbo Inlet is handcrafted from 100 percent genuine, dry/prepreg carbon fiber and finished with a sleek clear coat - a true performance upgrade that the LLY Duramax deserves.
