PPE's 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.

Features:

• Increases torque and power 
• Eliminates stock flow-restricting turbo inlet duct and resonator box
• Up to 25% larger flow passage cross sectional area than stock
• 100% dry/prepreg carbon fiber construction
• Available in two carbon fiber appearances - twill weaved and forged

Includes:

• Comes with special free-flow silicone coupler
