Construction & Design

The Momentum GT intake system is built with precision and durability in mind. Its roto-molded housing is crafted from black cross-linked polyethylene, a material known for its heat resistance and strength, which helps maintain the coolest possible air charge for improved combustion efficiency. The one-piece design eliminates the need for multiple components, reducing potential air leaks and simplifying maintenance.

The intake tube is also roto-molded and CAD-designed to optimize airflow dynamics, ensuring maximum power output without sacrificing fitment or reliability. The inclusion of billet aluminum fittings for the crankcase and temperature sensor adds to the system’s robust construction and ease of installation. Carbon fiber accents provide a premium look that stands out at car shows and on the street.

Performance & Sound

By delivering a higher volume of cooler air, the Momentum GT intake system improves engine efficiency and responsiveness. The large 360-degree radial flow air filter allows for increased airflow while maintaining excellent filtration, contributing to noticeable gains in horsepower and torque. Additionally, the intake produces a more aggressive induction sound, enhancing the driving experience without excessive noise.
