Injen Technology has once again excelled with its latest short ram air intake designed for the 2018-2021 Subaru WRX STI equipped with the H4-2.5L Turbo Engine. The SP1208 performance air intake system is the culmination of extensive research and development, offering a proven intake solution that enhances power and performance for your STI. It serves as a direct replacement for the restrictive factory airbox, enabling the turbo to breathe deeply and reach its full power potential with a simple drop-in installation. The best part is, no tuning is required to achieve the noted power gains.

The SP series of cold air intakes represents Injen's flagship systems within their lineup of traditional aluminum cold air intake systems. Injen Technology is a pioneer in the field of tuned air intake systems, holding four patents related to the tuning process of intake systems – a claim no other manufacturer can make. The SP series incorporates numerous patented tuning processes, including MegaRam (MR) Technology (Patents 7,359,795 and 7,669,571), Air Fusion (Patent 7,721,669), and other innovations that keep Injen Technology at the forefront of the performance aftermarket.

The core of the SP1208 intake is the 6061-T6 aluminum air intake tube, which offers an unobstructed pathway for highly efficient airflow. Injen's engineers have meticulously designed this intake to deliver high levels of safe power, along with a visually appealing under-hood appearance. Moreover, the Injen team has ensured a safe air-fuel (A/F) ratio across the power band.

Furthermore, the SP intake includes a fully serviceable Injen SuperNano-Web dry air filter, featuring an expanded filter surface area for increased airflow and unparalleled filtration. What's more, the Injen SP performance intake provides an audible and palpable power boost. It produces an aggressive and throaty tone that stands out in the aftermarket. If you desire a personalized touch for your intake, Injen offers this system in various finishes. To top it all off, this SP CAI kit comes with the exceptional Injen Technology limited Lifetime Warranty!
