2004.5-2005 Duramax LLY PPE Zilla Carbon Fiber Turbo Inlet Upgrade (115010060)

The PPE Zilla 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 compressor inlet flange, it enhances turbo efficiency, improves throttle response, and also increases airflow. The factory CCV port is preserved and connects to the threaded-on aluminum CCV adapter.

For optimal efficiency, the factory air cleaner outlet tube is trimmed after the flexible coupler where it starts to downsize. A specially engineered high-flow silicone coupler seamlessly connects the factory plastic tube to the PPE Zilla inlet, ensuring unobstructed intake airflow. Additionally, the factory plastic turbo resonator is removed, which declutters the engine bay and also unmutes the turbo sound. 

The PPE Zilla Turbo Inlet is handcrafted from 100% genuine, dry/prepreg carbon fiber and finished with a sleek clearcoat - It is a true performance upgrade for you LLY engine.
