Duramax Carbon Fiber Air Box Lid

The PPE Zilla Carbon Fiber Air Box Cover is an exceptional upgrade to your GM 3.0L Duramax.  It’s handcrafted from 100% genuine, dry/prepreg carbon fiber and finished with a sleek clear coat - such high-grade materials and craftsmanship are typically only seen in supercars. The PPE Air Box Cover not only boosts performance but also adds a striking look that sets your Duramax apart from the rest.

Unlike competitors’ air box designs that compromise maximum airflow for low-end response, The PPE Air Box Cover ensures accurate air fuel ratio and optimal efficiency across the entire spectrum.  It retains all stock mounting positions, guaranteeing perfect fitment and hassle-free installation.

The PPE Air Box Cover also has a built-in velocity stack. This element is often overlooked by competitors but is crucial for engine performance. The velocity stack ensures smoother airflow, increased air intake, and better throttle response, contributing to improved fuel efficiency and overall engine responsiveness.

Pair the PPE Zilla Carbon Fiber Air Box Cover with the PPE Zilla Intake Tube for the ultimate intake system for your 3.0L. This powerful combination delivers unbeatable throttle response, smooth airflow, and increased air intake, all while achieving a 37% weight reduction compared to stock components.
