    Grimmspeed 2015-2020 WRX Intake

    Inspiration for the StealthBox Intake came from internal discussions about what we wanted from an intake system for the 2015+ WRX. 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+ WRX engine bay instead of a shoebox stuffed into the fender area.

    Features

    • Low-profile heat shield protect air filter and MAF sensor
    • Utilizes factory scoop for fresh air supply.
    • Custom performance air filter with built-in velocity stack.
    • High-flow CNC bent and laser cut aluminum tube.

    Benefits

    • +32wtq (14.3%) and +21whp (9.6%)
    • Designed in CAD - Perfect mating with the factory turbo and ram-air scoop
    • Low bend angle aluminum tube - Minimize restriction and maximize performance
    • Shielded MAF sensor placement - Protects MAF from heat, which increases accuracy of readings
    • Made in the USA - Manufactured right here in Minnesota

    Please Note:

    • Take care to install the air filter onto the intake tube properly. Push the filter onto the tube no more than 1" before tightening the clamp. This will ensure that the velocity stack within the filter is allowed to function properly!
