Upgrade your Subaru WRX STI 2018-2021 with the aFe Takeda Momentum Pro 5R Cold Air Intake System, designed to maximize engine performance and efficiency. This system features a large five-layer Pro 5R filter, measuring 7-1/2 inches in height with a 3-1/2-inch flange, providing a high-flowing air intake for increased power gains. The filter's inverted top design offers more surface area for longer service intervals and optimal airflow. The filter-to-housing interface ensures a secure fit and efficient filtering, capturing cooler, denser air from the included dynamic air scoop and additional intake inlet in the fender well, which enhances throttle response and overall engine performance.
The one-piece housing is crafted from heat-resistant cross-linked polyethylene (XLPE) polymer, resulting in a durable and sealed enclosure that simplifies installation and maintenance. The clear sight window allows for easy inspection and monitoring of the filter's condition without disassembly. The intake tube is computer-designed and dyno-tuned to optimize airflow and maximize power output, achieving gains of +21 horsepower and +56% airflow over the factory intake. Its heat soak resistant XLPE material maintains performance even under high-temperature conditions, ensuring consistent power delivery.
Installation is straightforward with included stainless-steel clamps and silicone couplings that provide strength and durability. The system's minimal parts design reduces installation time while ensuring a secure fit. The intake setup outperforms the factory system, delivering increased airflow and throttle response, making it suitable for street and track use. This product is not CARB approved but is an excellent choice for enthusiasts seeking improved engine performance and a high-quality, durable intake upgrade for their Subaru WRX STI.
