Bring Supercar Craftsmanship To Your Duramax Engine Bay

Pop the hood and this PPE Zilla Carbon Fiber Air Box Lid instantly changes the way your 3.0L Duramax looks and feels. Handcrafted from genuine prepreg carbon fiber, it delivers a level of fit and finish usually reserved for high end performance machines. Beyond the visual impact, the lighter construction reduces weight over the factory lid, helping the intake system respond more quickly to throttle input. Additionally, smoother and more controlled airflow supports better engine response during everyday driving and spirited acceleration. This upgrade is designed to work across the entire RPM range, so performance gains are not limited to just one driving scenario. If you want a functional performance upgrade that also adds serious underhood appeal, this air box lid delivers on both fronts.

Engineered Airflow That Supports Efficiency And Response

This carbon fiber air box lid is designed to maintain an accurate air fuel ratio while improving airflow efficiency throughout the RPM range. The integrated velocity stack plays a critical role by smoothing incoming air and reducing turbulence before it reaches the intake tract. Furthermore, the prepreg carbon fiber construction provides exceptional strength and heat resistance while keeping overall weight to a minimum. PPE designed this lid to retain all factory mounting points, ensuring OEM-level fitment and a straightforward bolt-on installation. When paired with the PPE Zilla intake tube, the system achieves a substantial weight reduction compared to stock components while improving throttle response. Built specifically for 2020-2026 GM 1500 Sierra and Silverado trucks with the 3.0L Duramax, this upgrade is a smart choice for performance minded owners who value precision and quality.
