Construction & Design

The Momentum GT intake system features a one-piece sealed housing constructed from heat-resistant cross-linked polyethylene (XLPE), providing excellent durability and resistance to heat soak. This material choice helps maintain cooler intake air temperatures, which is critical for maximizing engine performance. The housing’s patent-pending filter-to-housing interface allows for the largest possible air filter, measuring 8 inches tall with 360-degree radial flow design. This unique inverted top filter increases surface area, extending service intervals and improving filtration efficiency without the need for oiling.

All hardware, including stainless-steel T-bolt clamps and silicone couplings, is selected for longevity and corrosion resistance, ensuring the system remains secure and effective under demanding conditions.

Performance & Sound

Engineered for performance, the aFe Momentum GT intake delivers measurable gains in horsepower and torque, enhancing throttle response and overall engine efficiency. The dyno-tuned intake tube optimizes airflow dynamics, contributing to these power improvements. Additionally, the system produces a more aggressive intake sound that enhances the driving experience without being overly loud or intrusive, making it suitable for both street and off-road use.
