Enhance your Subaru WRX STI's performance with the Injen EVO1206 Evolution Air Intake System. Featuring a roto-molded housing and ram air scoop, this system is designed to capture maximum cool air, feeding your turbocharged engine with improved efficiency. The 2-piece box design seamlessly integrates with the fully incorporated ram air scoop, providing an aggressive underhood appearance while maintaining an OE fit. Constructed from durable polyethylene, the housing ensures long-lasting performance and protection from heat and debris. The enclosed plenum and front scoop lock securely in place with Injen's proprietary Shur-lok coupler, ensuring a leak-proof seal and optimal airflow.
The system includes a custom, dyno-tuned aluminum intake tube utilizing patented Air Fusion and MR technology. This tube produces significant power gains, with dyno testing revealing increases of up to 26 horsepower and 34 ft.-lbs. of torque, all while retaining factory-style fuel trims for safe operation. The SuperNano-Web dry air filter is engineered for maximum airflow and filtration, designed to work with the downward-facing orientation to maximize air volume and simplify installation. The filter's large surface area ensures consistent performance and easy maintenance.
Quality hardware components such as stainless steel band clamps with protective liners and reinforced automotive-grade silicone couplers ensure a secure fit and durability under demanding conditions. Installation is straightforward thanks to the kit's 3D-designed components, allowing enthusiasts to upgrade their vehicle quickly and with minimal hassle. This intake system not only boosts engine performance but also provides an aggressive intake growl under acceleration, enhancing the driving experience. Backed by Injen’s limited lifetime warranty, the EVO1206 system is a reliable choice for Subaru enthusiasts seeking increased horsepower, torque, and a commanding engine sound.
