Product Description

The aFe Power 50-70121T Momentum HD Cold Air Intake System with Pro 10R filter is a high-performance upgrade engineered for GM trucks and full-size SUVs equipped with the 3.0-liter Duramax turbo-diesel inline-six engine covering 2020-2024 model years. This cold air intake replaces the restrictive factory air system with a sealed, high-flow design that delivers significantly more airflow - roughly 60% over stock - helping unlock improved horsepower, torque, and throttle response without the need for additional tuning.

At the core of this system is a large 9" pre-oiled Pro 10R filter with ten layers of progressively finer cotton gauze media that maximizes airflow and filtration efficiency for both on- and off-road use. The sealed one-piece XLPE housing features a patented filter-to-housing interface and an integrated clear sight window, making routine maintenance simple and removing complexity from installation. With premium clamps, a durable silicone coupling, and a dyno-tuned intake tube that resists heat soak, the 50-70121T is designed for durability and performance. Note: this intake is not CARB exempt and is therefore not legal for sale or use in California or states with equivalent emissions laws.
