Give your 2020-2025 GM 1500 3.0L Duramax LM2/LZ0 a serious upgrade with the PPE Zilla Carbon Fiber Air Box Cover, available in Twill Weave or Forged Carbon Fiber.
This isn’t just a good-looking piece, it’s built for performance. Made from 100% dry carbon fiber and finished with a sleek clear coat, it gives your engine bay that next-level style while delivering real gains. Unlike stock air boxes that choke airflow, this cover is designed to keep things smooth and efficient, improving air-fuel ratio, throttle response, and overall performance. It’s a direct fit, using all the factory mounting points, so installation is simple, no mods, no hassle. The built-in velocity stack is a game changer, increasing airflow and improving throttle response, something most other covers don’t even consider.
For the best performance boost, pair it with the PPE Zilla Intake Tube (115020360) and get max airflow, better acceleration, and a 37% weight reduction compared to stock. More power, better efficiency, and a killer look.
