GrimmSpeed Stealth Box Cold Air Intake Black 2015-2021 STI

Inspiration for the Stealth Box Intake came from internal discussions about what we wanted from an intake system for the 2015-2021 STI. Of course, performance is the highest priority, but at GrimmSpeed so much more than that goes into a product. We wanted an intake that purred quietly under normal driving circumstances but would roar at wide-open throttle. We wanted an intake that looked at home in the well-sported 2015-2021 STI engine bay instead of a shoebox stuffed into the fender area. From here, the SteathBox was born. We took the concept one step further and referenced the F-117 Nighthawk as inspiration for the stealthy look of the GrimmSpeed heat shield. It should come as no surprise that the performance it packs is equally unique.
