Injen's cold air intake replaces the factory air box on the Scion FR-S and Subaru BRZ with a wrinkle-black tube and cone filter that draw cooler air from outside the engine bay. It ships with the hardware needed for installation and is aimed at owners who want more intake sound and a modest top-end gain without a tune. Compared with stock, it frees up engine-bay space and adds induction noise; compared with pricier sealed-box intakes, it is an open-element design that can heat-soak in traffic. Owners typically report a sharper throttle feel and a deeper tone rather than a large power jump.

Owners of the FR-S and BRZ generally describe the Injen intake as an easy first mod that sharpens throttle response and adds a noticeable intake growl. Most say the power gain is small and felt mostly at higher rpm, and some note it gets louder than expected on the highway.
This cold air intake system from Injen replaces the factory intake air box, mounting in the same location. It draws in cooler, denser air to help produce power across the power band.
The kit includes all the hardware needed for installation.
