GMC Sierra 2500 HD Performance Air Intake - Wehrli - 4in, High Flow, Aluminum, Dry Filter - Sparkle Granny Smith - 2020-2025. This direct-fit kit replaces restrictive factory parts to help your L5P 6.6L breathe cooler, denser air.

Constructed with a 4 in mandrel-bent aluminum tube and a 10-gauge aluminum air box and lid, this system draws fresh air from the hood Ram Air duct and inner fender for improved throttle response and reduced intake temperatures. Smooth, large-radius bends promote airflow and add a more pronounced turbo note under acceleration. The dry filter with an Outerwears pre-filter cover helps keep debris at bay, while stainless T-bolt clamps and high quality silicone couplers provide a durable, leak-resistant connection. No tuning required and fully compatible with stock trucks. Note: disabling the factory air filter monitor is necessary to prevent service messages.
