• Engineered with fewer components for a straightforward installation using factory mounting points

Filter Options

The Momentum GT Cold Air Intake is available with two high-performance filter options to suit different preferences and maintenance routines:

• Pro 5R (Oiled): A 5-layer cotton gauze filter media that progressively filters air for maximum performance and airflow. It is washable, reusable, and ideal for both street and track use.
• Pro DRY S (Non-Oiled): A 3-layer synthetic media filter that requires no oil, offering easy maintenance while maintaining excellent filtration and airflow. Perfect for daily drivers.

Construction & Design

The intake system’s housing is crafted from high-quality cross-linked polyethylene (XLPE), a material known for its outstanding heat resistance and durability. This roto-molded housing not only protects the air filter from engine heat but also optimizes airflow dynamics. The inclusion of a clear sight window allows for quick visual inspection of the filter’s condition without removing the intake cover, adding convenience to routine maintenance.

The intake tube is precision-engineered using computer-aided design and dyno testing to ensure it delivers maximum airflow while maintaining a perfect fit with factory components. The tube’s high-quality plastic construction includes a molded fitting for the air temperature sensor, ensuring seamless integration with your Jeep’s original equipment.
