PPE Carbon Fiber Turbo Inlet Upgrade Kit 11-16 GM 6.6L Duramax LML

Is your factory LML turbo inlet choking airflow and holding your Duramax back? The PPE Zilla Carbon Fiber Turbo Inlet Upgrade Kit is designed to eliminate the restrictive factory plastic inlet and resonator system that limits turbo efficiency, airflow, and throttle response on 6.6L Duramax trucks. Whether your truck is tuned, towing heavy, or simply needs to breathe better, this upgrade delivers noticeably quicker spool-up, improved airflow, sharper throttle response, and a more aggressive turbo sound the moment you hit boost. PPE engineered the Zilla inlet to reduce pressure drop and turbulence before the compressor, helping the turbo operate more efficiently while increasing volumetric airflow and usable engine torque. On top of the performance gains, the carbon fiber construction completely transforms the engine bay, delivering a high-end, supercar-inspired appearance that instantly stands out whenever the hood is opened. The PPE Zilla inlet is built for lightweight strength, long-term durability, and premium fit-and-finish that far exceeds the factory plastic design. Each inlet is finished with a high-gloss clear coat and available in both twill-weave and forged carbon finishes to match the look of your build. PPE designed the system for true OEM-style fitment with a direct bolt-on installation that reuses factory mounting locations while retaining the factory CDR valve system. The kit also includes a flexible airbox coupler, stainless hardware, and a dedicated CDR adapter plate, ensuring a clean installation and proper sealing. PPE’s extensive testing and calibration focused on maximizing airflow without sacrificing drivability, making this one of the most effective and visually impressive intake upgrades available for the LML platform.
