GRIMMSPEED STEALTHBOX INTAKE - 15-21 SUBARU STI

You've been asking for this bad sally for a while and it's finally here. The intake the for the 15+ STI can be thought of as a hybrid of the tube and filter used in the 08-14 WRX intake and the Stealthbox heat shield used in the 2015+ WRX intake. Small design changes were made, but the overall fit and performance is approximately the same.

Quick Specs

Hybrid Cold Air/Short Ram Design - Combining the advantages and eliminating the negatives of both traditional intake designs

Air straightener - Dimensionally mimics the factory configuration for accurate MAF sensor readings

MAF sensor location - Inside heat shield, isolated from engine bay heat

Custom reusable high flow air filter - Integrated velocity stack entrance smooths incoming air

StealthBox Heat Shield - Sleek, unique design looks KILLER in your engine bay and keeps the heat of the engine bay from affecting performance

Made in the USA - Right here in Minnesota, in fact

30min Installation - Extremely simple with our written and video guides

Why GrimmSpeed?

Sometimes, this explanation is long and technical, especially where performance is concerned. This time, it's simple. The GrimmSpeed engineering and manufacturing teams are known for designing and producing products that use high quality materials, offer perfect fitment and superior craftsmanship and are durable. These intakes are no different and feature the proven performance of the 08-14 WRX EJ motor intake (third party results coming soon) with a look and feel that set it apart from the competition. With the Stealthbox intake heat shield, you no longer need to look like you've got a shoe box hanging out where your factory airbox used to be.

Of course, like all GrimmSpeed products, we stand behind these kits 100% and our goal is to offer you a customer experience that makes you want to stand behind them as well.
